Hi. I have two gentoo systems. Both systems run with the same hardware (on the same PC).

System 1:
- Older system not updated for many months
- Kernel 4.9.x
- No pulseaudio

System 2:
- Up to date
- Kernel 4.19.86
- No pulseaudio

My headset is connected either to the mainboard directly or to the monitor (sound over hdmi). The current card/device was set through .asoundrc (defaults.ctl / defaults.pcm) inside /home.

I have two problems with the second system. On the (older) first system I do not have these problems.

Problem 1:
When restoring from suspend there is no sound over hdmi. I need to restart my system to get the sound back.

Problem 2:
The sound "over mainboard" is crackling / popping. The sound is not clear. No problems with sound over hdmi.

I would like to know why this happens and how I could solve it. I will gladly provide logs or further information. However, I must be told which logs and how I can create them.

Thank you.

On the system 1 there is

$ cat /proc/asound/card1/pcm0p/sub0/*
...
buffer_size: 16384
...


On the faulty system there is


$ cat /proc/asound/card1/pcm0p/sub0/*
...
buffer_size: 8192
...

No idea how related and how important is it.
