Additional info: this problem only concerns the onboard HDMI and SPDIF audio and the Hifi shields.
When using a USB Audio DAC, things appear to work just fine.
I am trying to use a HiFi Shield 2 with Odroid-c2 and I am getting no sound. When I connected to a monitor, I could see i2c kernel token error messages in the logs. I tried reformatting, but still no luck. When I try to choose the dac in Volumio, I only see the option for Shield HiFi, not HiFi-2. The mixer type says only ānoneā and āsoftwareā. Neither options work. Is there a need to edit any files in order to enable on the c2? I saw the instruction for the c4, but the c2 image doesnāt have the file mentioned in the c4 wiki/op.
aplay -l does not list pcm512x
Hopefully someone can help.
volumio@volumio:~$ aplay -l

Subdevice #0: subdevice #0There were no previous reports that this is not working, the C2 image already exists for several years.
Let me know the exact version you are using, otherwise there is no chance to help.
The token error messages are āsort ofā ok, it is the result of probing for i2c interrupts addresses, not nice but it it the way the C2 kernel reacts to it. Canāt change that unfortunately. After Volumio has gone through the startup procedure, you should not see anymore of them.
Basically, you will never have a Hifi Shield/Shield+ and a Hifi Shield 2 in Volumio playback options at the same time.
When it only shows Hifi Shield/Shield+ then it means it did not recognize your Hifi Shield 2 (all the probes where nagative).
Sure it is a HiFi Shield 2 or did you install any other hardware which might be conflicting with the i2c bus/interrupt address, which Shield 2 is using?
Please read this IMPORTANT notice!
Iām working on an update for all supported Odroid devices.
They should be available sometime tonight.
New updates are available, either use OTA (System Menu ā System ā Check Updates) or reflash.
Of course, many other changes flowed into this version.
Refer to the changelog on the download page for a detailed list since your last update.

Hi,
Odroid c1+ owner here.
I have encountered few issues:
-
SSH not working (connection refused) but WebUI up and running (im 100% sure iām not the issue here since with the same history command 30s before the ssh was working properly). The only things i did was manually mount a samba storage (here lies the second issue) and connecting a WiFi dongle without configuring it (i had Ethernet cable in). After resetting via webui the ssh came back (iāll soon test with WiFi dongle again)
-
Canāt mount SMB shares i normally use with other devices. I have the same error (-95) found here
https://github.com/volumio/Volumio2/issues/1517but when i usesudo mount -t cifs -o guest,ro,dir_mode=0777,file_mode=0666,i ocharset=utf8,noauto,soft,vers=2.1 //192.168.1.52/Disco /mnt/Discothe share is mounted and i can browse it via ssh but no luck in the webui -
Wifi dongle not recognized with
sudo iwconfig. The device according to lsusb is a BCM4323, maybe iām missing the driver?
FIXES
- Not yet
- I added
vers=2.1in the option and it was mounted properly
Any help would be great
- no idea what causes this issue. In the 6 years we support C1 this has never been reported before.
- Adding āvers=ā¦ā to the options is mandatory for all smb servers running a smb version > 1.0
- Broadcom dongles are not supported in Hardkernelās kernel v3.10, there are no drivers for them.
Ouch thank you for the reply.
I do have another question iāve tried to install a driver but most likely it wont work.
When i do factory reset is the system restoring its state and removing all the installed things or is is just a matter of configuration?
Another thing that is driving me mad although it is not strictly related to odroid products is that music library scan stucks on pretty much all my folders.
Iāve seen posts about removing them but I will end up with 10 albums at most.
Could you please help me out on this?

error: Failed LSINFO: nullScanning issues are not C1-specific, I canāt help much with that.
As for the WiFi driver problem, I would advice to use another dongle, manually compiling and installing a driver is impossible without the proper kernel header files. I donāt have them.
I know, RTL8821AU, RTL8188EU and Atheros AR9721 dongles work.
Note, hot-plugging does not work well on a C1, make sure the dongle is fitted before booting.
Which product does contain one of those chip?
Also on my odroid c1+ the media library scanning is taking days, is there away to avoid it or reduce the time it takes? Can i save it?
Ever heard of google? 
Try āRTL8188EU dongleā 
You can also use Ralink 5370 dongles, some have an antenna.
Scanning a 12ā000 track NAS share takes approx. 30min here.
Iām afraid I canāt help with that, it is not C1-specific
Iāve tried with DSD files and even with DSD Direct the DAC is not reproducing them as DSD64/128/256. Instead they are converted to PCM 384/768Khz
On my Rpi 4 they are correctly reproduced instead (DSD64/128/256 logo on my DAC)
Any idea?
man oh man, could you please gives us some more info instead of us having to drag it out of you.
How am I supposed to know what DAC youāre talking about?
All USB audio devices, capable of DSD direct, need to be registered in the kernelās usb audio driver on the platform you use. Yourās is probably not in.
Start with a full log from the <your-ip/dev> page and post the link you get.
And also give the output from
lsusb
This gives me the DACās āVendorID:ProductIDā to check.
volumio@volumio:~$ lsusb

The DAC is a Topping D50 DAC and as i said on RPi4 it works.
Ill provide you the startup log as soon as i have access to the HW for more time
yes, this is a DAC with generic Thesycon firmware and is supported on modern kernels.
However, bad news, while checking I just noticed, that the C1 usb audio driver offers no DSD direct support at all and it cannot be patched either. The kernel is way too old, DoP is all you can have.
This also makes your log obsolete, Iām sorry
After reflashing the sdcard and changing HDD on NAS the music library is imported much faster but i have a big issue.
Iām now suffering of unresponsiveness of the system and mpd crashing during music library import.
Basically imports works flawlessly till around 620 tracks (i believe its the total) and then the system become super unresponsive and kswap0 kicks in (i guess killing cifs and mpd process).

Could this be related to the low RAM available?
I tried volumio@volumio:~$ sudo echo 1 > /proc/sys/vm/drop_caches but nothing changed
Unfortunately when it freezes i canāt send the logs anymore but still journalctl -f has nothing relevant inside.
About the old kernel, have you ever look into this ?
https://armbian.hosthatch.com/dl/_old/odroidc1/
it seems it is based on kernel 5.10
Yes, I know Armbian very well and the great work they do to the community.
However, Armbian dropped regular support for the C1/C1+ a long time ago.
They have started something experimental, it it is without any i2s audio component because mainline support for s805 is very limited. It does not support eMMC, no usb hot-plugging etc.
For us this is useless as a reference.
So, please accept that there will be no more 3.10.y kernel updates, neither from Hardkernel, from Armbian or from us.
I have no intention to invest time to figure out if there is an alternative way to get DSD support to the C1 kernel. As said before, DoP is all you can have.
Iām really sorry, but it is the way it is 
I got your point, still i use no i2s audio, i use USB DAC which is always plugged in (hot-plugging not needed) and i do have an SDCard so i just felt it could have been useful.
Can you help me out with the issue iām facing above?
I have the image running here on 2 old C1+ boards and do not experience any problems with a NAS library and approx. 12ā000 tracks.
Not with this image or any of the previous.
Looks a bit like power issues, can you check without the usb dac or any other peripherals connected?
I was able to catch the dmesg

it seems like it is indeed a memory issue (i have 1.5Gb files in my library btw)
When this starts
[ 315.364088] _hcd_isoc_complete:Uknown urb status -2
[ 319.800116] WARN::urb_dequeue:964: urb->hcpriv == NULL! urb = da983e00 status=-104
the audio start to stutters probably due to resoruces, the question is why mpd goes so high in memory consumption
So i start to understand whatās the issue here
Previously iāve installed the following mpd
to make volumio-ytcr work better (and apparently no issues were present aside from the scanning).
So what i did was reflash the official image and start the library scan.
It turned out that after 30min the library scanned only 15 songs.
With this new mpd the library scan went so much faster (60 albums in like 5s) but it always ends up eating too much memory and crash at the end.
Iāve also noticed that if i turn off via volumio ui half-way the scan, it always restarts from zero.
Unfortunately i can say for sure that the old version would end up completing the scan properly.
