My Remote control is LE without usb dongle and just “connect” unfortunately, is not enough.
How to create a boot script (or what?) that will execute two commands: bluetoothctl and scan on? Thanx.

Updated to 4.017 without issues on both my Volumio installs on RPi3B and Rpi4B.
One thing I do notice, however, is that the startup volume level setting is applied 30 secs or so after startup on both units. In other words, if I manually set the volume to, say, 90% and reboot, it takes a full 30 secs after startup before it applies the preset level of 60% (as shown by the volume level graphic - thank you for adding that 
). Don’t think there was this much of a delay when you fixed the startup volume issue a few versions back.
Not a major issue, but in the above scenario, if you start playback immediately on reboot or have the Autostart plugin running with the delay set to less than 30 seconds you will get a blast of sound before it resets to the preset startup level.
Regards,
Thanks for the support and I have solved the problem related to the “Now Playing” screen display.
However, there is a problem related to some music file formats in my library - *.APE and DSD. I use DAC SMSL SU9 Pro (Output device: SMSL USB Audio), when listening to music with Volumio 3.xxx everything is normal, and I do not encounter the following problems:
- If DSD Playback mode is selected as DSD Direct, Volumio cannot play the music file, meaning the seek bar is still, and of course there is no sound;
- If DSD Playback mode is selected as DSD over PCM, there are 2 cases: (i) DSD Auto volume level + Volume Normalization are both OFF, there is sound, but the noise is many times louder than the music. (ii) If Volume Normalization is OFF, the noise is lost, but the original sound is distorted, like the singer is chewing gum and singing slowly.
- In such cases, the Music Library is completely wiped out, and a rescan is required.
Hopefully the updated version will restore at least what the 3.xxx versions did.
Best regards./.
Hi @DungLD
Have you tried to increase the buffer audio size in playback option ? Just rise it to 16 MB to see if there is any different behavior.
Regards
On what kind of hardware are you running V4?
My hardwares:
Memory card: SD 16GB
Computer: Pi5
Storage: SSD 512GB.
DAC: SMSL SU9 Pro (https://bitly.li/RxpL)
I have set the audio buffer size to 12MB as it was (haven’t tried 16MB yet).
I will try with the size you suggested.
- Can you post a log when the issue occurs?
- Is this also happening after a reboot without switching inputs (like optical or Bluetooth). If yes, - Go to Volumio’s Playback Options and manually reselect the DAC as the output device. This refreshes the connection without needing a full reboot.
- Some users have reported intermittent distortion or dropouts with the SU9 Pro due to suspected firmware bugs. A workaround is toggling output modes (Balanced → Unbalanced → All Line Out → Balanced) to reset the DAC’s internal state.
- Have you tried switch the USB cable, to a high quality cable
@nerd
Any other suggestions on your sleeve?
I understand your comments.
However, the change between Ver. 3.xxx and Ver. 4.017 is simply that I installed 02 versions of Volumio on 02 different SD memory cards, and plugged/unplugged these cards. The whole system has no changes, including all connections.
This allows me to deduce that the above situation comes from the software.
Specifically, when inserting the SD card ver. 3.xxx, playing music from APE, WAV, FLAC, DSD formats is normal, for all modes Balanced, Unbalanced, All Line Out of the DAC (of course the sound is a little changed). Switching songs, browsing the music library is also smooth, responsive.
Listening to music from Bluetooth, optical (from TV) sources is also normal.
Regarding the issue log, I will find out how to get the log file because I really have no experience.
Sincerely.
Hey @DungLD,
1. Get Volumio log link (from UI):
- Boot into the Volumio 4.017 SD card.
- Reproduce the issue: try playing a DSD file (DSD Direct and DoP modes), let it fail.
- In your browser, go to:
http://<volumio-ip>/dev
(Replace<volumio-ip>with your actual Volumio IP address, e.g.,http://192.168.1.100/dev) - Scroll down to the bottom.
- Click the button: “Send log or bug report”
- Wait for the upload to complete.
- Copy the full URL it returns (starts with
http://logs.volumio.org/...) - Paste that URL here.
2. SSH diagnostics - basic command set:
-
SSH into the Pi 5:
ssh volumio@<volumio-ip>Default password is:
volumio -
Once logged in, run the following and save output:
aplay -lcat /etc/mpd.conf | grep -A15 "audio_output"cat /var/log/mpd.log | tail -n 100journalctl -u mpd --no-pager --no-hostname | tail -n 100dmesg | tail -n 100 -
Optional: If available, post your
asound.confor~/.asoundrc:cat /etc/asound.conf
Post the output of each command or upload a pastebin/gist link if it’s long. Once this is done, I will help analyze what broke between Volumio 3 and 4 in the DSD/DoP handling.
Kind Regards,

Following your instructions, I have done the following:
- Logs:
URL: http://logs.volumio.org/volumio/0YbEJzo.html - Commands:
I have done it on Putty application.
Because the result is quite long (19 pages), I have copied it into 01 file. - asound.conf file:
- Other:
It seems that I forgot to download the “audio_output” file (is that right?). If so, I will send it later.
- I have recorded short clips related to the DSD music playback system with Volumio 3; Volumio 4 with DoP mode and DSD Direct (the language on the screen may be strange to you, but you certainly understand). I don’t know if the forum allows sending these clips, or you can share your email so I can send them.
Best regards

Hey @DungLD,
Thanks for the detailed logs and SSH outputs - they were very helpful.
From the analysis so far, we’ve identified that FusionDsp is currently enabled, and this plugin rewrites the audio path in Volumio using ALSA routing logic incompatible with DSD Direct or DSD-over-PCM. Specifically, it cannot handle raw DSD_U32_BE format, which leads to the MPD process crashing and your playback failing. This matches the error seen in your log:
ALSA lib pcm_volumioswitch.c:189: unable to set sample format to DSD_U32_BE
mpd: pcm.c:728: snd_pcm_name: Assertion `pcm' failed.
To continue diagnosing and confirm this is the root cause, please follow these exact steps:
Step-by-step instructions
-
Go to Volumio UI - Settings - Plugins.
-
Disable the following plugin:
- FusionDsp
-
Also disable (for safety during test):
- Now Playing
-
Reboot Volumio.
-
After reboot:
- Go to Playback Options
- Make sure your Output Device is still set to SMSL USB AUDIO
- Set DSD Playback Mode to DSD Direct
-
Attempt to play a DSD file from your local library.
Then:
-
Visit:
http://<volumio-ip>/dev- Scroll down and click Send log or bug report
- Copy the log link and paste it here
This will confirm whether the core system (without audio-altering plugins) can properly handle DSD playback on Volumio 4.017 with your DAC.
Once we have that log, we’ll proceed step-by-step to confirm if plugin interference is the root cause, or if deeper changes are needed.
Kind Regards,

I have been having an issue where sound seems to stop. There’s no output sound and the UI timestamp is also stopped but if I refresh the page it will increase. So it seems like the song is playing just no output sound. If I hit the play button sound starts again.
If I go into /dev I can see the song changes as well once its done.
I pulled logs here. Let me know anything else I can get. I have had it happen a few times this time I woke up and found it had happened overnight so I’m not sure exactly when it started. I can try to get a log next time it happens so you have a clearer time frame.

This is a Rasberry Pi 5 with a HiFiBerry DAC+ Pro and streaming from a NFS NAS.
Edit: It happened again just now

I think it’s smart to clean/repair your mp3 files first.
Your log contains about 350+ errors. If Volumio tries to play one of these broken files, no clue what will happen.
Here are a few of the many:
[src/libmpg123/id3.c:INT123_parse_new_id3():1086] error: Whoa! ID3v2 frame claims to be larger than the whole rest of the tag.
[src/libmpg123/parse.c:skip_junk():1317] error: Giving up searching valid MPEG header after 65536 bytes of junk.
[src/libmpg123/id3.c:process_comment():584] error: No comment text / valid description?
Note: Illegal Audio-MPEG-Header 0x00000000 at offset 5103249.
[src/libmpg123/parse.c:wetwork():1406] error: Giving up resync after 1024 bytes - your stream is not nice... (maybe increasing resync limit could help).
2025-07-23T11:54:44 mpg123: mpg123_read() failed: A generic mpg123 error.
error: scanFolder - failure to stat '/mnt/NAS/proxmox-share/
Thanks @Wheaten I had this same setup on the previous volumio and didn’t have an issue.
How would I clean up or repair my MP3s?
- Use your NAS internal program to scan/repair the disk.
- Get ride of the huge broken playlist you’re trying to load as this also contains errors, like:
error: scanFolder - failure to stat '/mnt/NAS/proxmox-share/(78 errors) - When all files have been scanned/repaired use an external program like mp3tag, mediamonkey, bliss to clean and/or validate your tags.
- Next throw away the mount in Volumio
- Reboot
- Setup the mount and scan the library again.
- When completed examine the log for errors.
- Disable FusionDsp plugin.
- Disable Now Playing plugin.
- Reboot Volumio
- Output Device set to SMSL USB AUDIO & DSD Playback mode is DSD Direct Mode
- Log URL:
5.1. http://logs.volumio.org/volumio/yM7ZZV3.html
5.2. http://logs.volumio.org/volumio/bfzxdh3.html
I did the steps as you suggested. Great. The result is that Volumio 4 can play DSD music format with DSD Direct Mode, even when I enabled the Now Playing plugin (however, I tried to play APE, CUE formats music but it still didn’t work).
I sent 02 Log links (1. Only play DSD music; 2. Play *APE).
Another great thing (as attached image) is that my DAC correctly displays DSD format (circled in red), which previously Volumio 3 disappeared and displayed as PCM, which I think is due to the update, or the USB cable quality has decreased. So Volumio 3 also has problems recognizing this DAC.
So the problem is with the FusionDsp plugin.
Hopefully the above tests will help you get Volumio 4 working with plugins. I didn’t bother disabling the FusionDsp plugin - since I don’t use it either, time consuming but hopefully useful for you.
Best regards
Dear Volumionauts,
We are officially entering pre-release phase for the Volumio Bookworm Beta. This marks a critical milestone in the evolution of Volumio 4 - the systems are in place, the architecture is stable, and we are stepping into the final stretch before full release.
What does this mean?
- The Beta is now feature-complete for Raspberry Pi and x86_64 (amd64) platforms.
- We are entering final integration and validation: all core components, plugins, drivers, services, and hardware support are now under release-grade scrutiny.
- Every bug, crash, or unexpected behavior must be addressed or explicitly triaged before GA (general availability).
- Ports to other boards (Odroid, RockPi, etc.) will follow after this milestone is secured.
This is a major systems achievement. The migration from Debian Buster to Bookworm involved:
- A new kernel toolchain and rebuild for all platforms
- Deep overhaul of the Bluetooth stack, MPD, ALSA routing, and CD handling
- Migration of backend services and plugin APIs
- New firmware integration and device compatibility matrix
- Stability across OTA upgrades, USB boot, and multi-architecture testing
The result is a modern, future-proof foundation for Volumio moving forward.
Expect the changelog to reflect only core changes. This announcement is about the status: Volumio Bookworm Beta is no longer experimental. It is now pre-release quality and ready for your help in testing, validating, and refining every edge case.
Let’s make this the smoothest transition Volumio has ever seen.
Kind Regards,
