dmesg taken after reloading snd_hda_intel
Description of problem:
After a while of normal audio performance (maybe a certain number of streams?) sound output from my snd_hda_intel chip (Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20] (rev 05)) on my notebook gets muted. This persists across restarts of pulseaudio, and even if I try to use ALSA directly (hence reporting to kernel).
There are no unusual messages in dmesg (attached).
Likely a regression -- I don't remember seeing this in kernels before 3.8.12. Will double check against 3.8.11 and 3.8.4.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Keep playing music/watching videos until the sound stops.
Additional note: It seems to only affect speakers (still have headphone output). Also, a suspend-resume cycle brings speaker output back.
Appears to be a hardware failure. Closing.
