I'm having audio issues with Debian for many months. The main problem is that i can't hear audio from the browser, but if i use VLC and i select the output device in the settings i can hear sounds.

I tried blacklisting other audio devices, changing their priority in alsa-base.conf, even installing a chromium extension to switch output device but nothing happened. How do i pick the default audio device?

Here's my /proc/asound/modules outuput:

0 snd_hda_intel
1 snd_usb_audio
2 snd_hda_intel

This is my aplay -l output:

saverio@Saverio-PC:~$ aplay -l

The device i'm interested in is the snd_usb_audio and the card 1: headset.

  • Are you sure you are using only ALSA, and not Pulseaudio? Try starting pavucontrol while the browser is running, and switch to the correct sink in the Playback tab. – dirkt Aug 8 '17 at 9:21
  • I deleted completely Pulseaudio some times ago because it was giving me many problems – Saverio Aug 8 '17 at 9:34
  • Please edit question with contents of your ~/.asoundrc. If you don't have one, make one and set the default device (google for instructions). – dirkt Aug 8 '17 at 9:55
  • Don't put solved in the title. Instead, please accept an answer if it solved your problem. – slhck Aug 8 '17 at 12:48

Making a ~/.asoundrc with the proper default device apparently solved the problem.
