Problem with headphones in Qubes-OS 3.2rc2

[York Keyser]

Hi List,

I think I have a problem with the sound on my Qubes-OS 3.2rc2. Sound
works fine with the speaker, but as soon I plug in headphones I can't
hear anything. I can see the that the sound is playing in the Volumen
Control but I can't hear anything. Also, it the Volumen Control shows
that the headphones are plugged in. Anybody with the same problem or is
it maybe a Layer 8 problem ;)

Regards York

I was just about to post the same problem, I'm guessing I have to pass a device to the vm I'm just unsure which one. I had my headphones plugged in when I started audacious in one of my vms I got this error message:

ALSA error: No suitable mixer element found.

ALSA error: snd_mixer_attach failed: No such file or directory.

when trying to play some of the songs I got this:

ALSA error: No suitable mixer element found.

ALSA error: snd_mixer_attach failed: No such file or directory.

ALSA error: snd_pcm_open failed: No such file or directory.

I'm updating my VM's and rebooting to see if it helps.

also forgot to mention, even after I unplugged the headphones I'm having the same issue

If they're just regular headphones, I don't think you should have to pass any
devices to any VM. Try checking in the settings for your dom0 sound mixer
(e.g., KMix). Make sure that the headphone volume level isn't set to 0 and
that the associated device isn't disabled.

Hi list,
problem solved, there was a second entry for Headphones in the alsamixer
settings, which was not shown in the PulseAudio Control. This entry was
muted that's why I didn't hear anything. Anyway, thanks for your help
and quick response to my layer 8 problem ;)
