Audio not active after suspend; too high with Nautilus previewer

English Multimedia

Hi, I have two problems with audio settings.

  1. after suspend, I don’t have audio with speakers or headphones. It’s totally mute;
  2. I cannot set a low audio volume with Nautilus previewer, so for example previewing a video is simply too high.

Here some information from my audio card:



localhost:~> cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version k5.14.6-1-default.

localhost:~> cat /proc/asound/modules
 0 snd_hda_intel
 1 snd_hda_intel

localhost:~>  cat /proc/asound/cards
 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xa0810000 irq 58
 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xa0814000 irq 59

localhost:~> sudo head -n 1 /proc/asound/card0/codec*
Codec: Intel Haswell HDMI

I have only alsa family installed.

What should I do to solve these two problems? I can provide information if needed.
