UI doenst response after Mixer to Software change

Volumio Development Bug reports
1

Hi,

i have a Raspberry 2 with an Hifiberry Mini Amp. With Volumio 2.163 and 2.175 I has the problem that if I change the “Mixer Type” to software, the UI doenst response anymore. 2.118 works fine for me.

After a reboot the settings are gone and back on “none”

As the output device I’m using “Hifiberry DAC” with which I get the startup sound at 100%. So basically my Hardware is ok.

Volumio.log doesnt show any problems

2017-05-19T11:55:24.838Z - info: Asound.conf file written

Dmesg only show this at bootup

[ 15.671856] snd_bcm2835: unknown parameter 'index' ignored [ 15.805576] snd-hifiberry-dac soc:sound: ASoC: CPU DAI (null) not registered [ 15.817925] snd-hifiberry-dac soc:sound: snd_soc_register_card() failed: -517

The systemctl status of volumio, volumio-network and volumio-reload-daemon are active

Any ideas? Does anyone else has this problem changing mixer type to “Software”?

Hi,

sadly this problem still exists. Does anyone have a idea how to solve this? Or is there more information needed.

I did a new install with 2.201
After this i switched to Hifiberry DAC which gives me after a reboot 100% output
Then I tried to switch to “Software Volume Control”
20 Seconds later Volumio doenst respond anymore but i can still connect via ssh.

Here is the log after switching to “Playback Options” and changing “Mixer Type” to “Software” till the system doenst response anymore

I have been struggling with the exact same issue, same setup as yours.
This fixed it:
I edited the config.json file in the /data/configuration/audio_interface/alsa_controller folder. Changed mixer_type value from “none” to “Software”, saved the file and did a reboot.
Now this shows up in the Playback Options menu:
Mixer Type: Software
Mixer Control Name: Software Volume Control
Default Startup Volume: 80 (I changed the value in the config.json file)
:smiley:

Just discovered that it does not fix the issue of not being able to adjust the volume. It only changes on the UI :confused:
