Chrome sound issue with USB Dac

ppkstat · January 15, 2022 at 3:57 AM

Hi there,

I am trying to get the chrome add on to output sound with my new usb dac connected to my NUC and I am not getting there at all despite all my attempts.

It should me noted that audio and libreelec never worked out of the box with my NUC. However I used to solve the problem by using plughw: 0,3 which redirected the audio to the hdmi output. However doing something similar in this case doesn't help.

Audio setup:

aplay -l output:

Based on these, and if I am not mistaken plughw: 2,0 should work an an output device. Instead Chrome crashes and doesn't even start. In fact it crashes with anything I try as a custom audio device. Even plughw: 0,3 is not working with this installation I don't know why.

I tried commenting the last lines of chrome strartup (the ones about pulse audio) but it didn't help. I also tried kodi mixer but it is not working as all entries appear to be unoccupied.

All audio apart from Chome works as indented. Any leads?

Debug logs?

There you go. I hope I did everything correctly.

After pulseaudio support you have to use ALSA: or PULSE: prefix, e.g ALSA:plughw:2,0.

The plugin crash if not using a prefix is likely be fixed in the near future.

Yes it's working perfectly now! Thank you!

I wish I had read 'this thread' last night, when I had updated a friend's Libre system to the 10.0.1 version.

Chrome would not launch if 'custom audio device' was selected (regardless of output device, though I was specifically attempting to use the DisplayPort output 0,3, from the same vendor-list of devices encountered by ppkstat).

Don't worry. Use

Code

ALSA:plughw:0,3

it will work (provided you're using this device).
