Hello,
After I had a larger system update I no longer have sound. I use a headphone.
% lspci | grep Audio
00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] SBx00 Azalia (Intel HDA)
01:05.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] RS880 HDMI Audio [Radeon HD 4200 Series]
02:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cypress HDMI Audio [Radeon HD 5830/5850/5870 / 6850/6870 Rebrand]
I'm using Intel HDA
% bash alsa-info.sh --upload
url with the info:
http://alsa-project.org/db/?f=a59113422 … ac415c7753
Any idea what might have gone wrong? Thank you.
Edit: I had a kernel update if that is any help.
Turned out the dynamic power control in alsamixer was somehow disabled
Nope that was not the issue just went afk for a while and suddenly my sound is no longer working!!!?!?!?

Edit: After restart it works again ... I have no idea what is going on. in alsamixer my loopback device got enabled and after enabling it eh sound worked again. Before reboot it was enabled but the sound still didn't work after some time afk. I have no idea.

What I found out so far is that after reboot I need to call up alsamixer and enable dynamic power control and loopback. It get's diabled by default on reboot. It's annoying.

I was having that problem when I did the update and there was a new update and now the audio works again.
