I have an issue with sound during music and sometimes video |
2 |
playback. Usually it fades out (gets quieter) and then fades back in a |
3 |
couple of seconds later. This happens randomly maybe a couple of times |
4 |
in an hour or two, but can sometimes go several hours without |
5 |
issue. It has happened with quodlibet and mocp (audio - mostly ogg, |
6 |
some mp3) and with vlc (video - mostly mp4/m4v). I don't use other |
7 |
music/video software enough to notice it there. |
8 |
|
9 |
During heavy load (like emerging packages), the sound will sometimes |
10 |
stutter or even stop and then restart a few seconds later. The |
11 |
computer is a few years old, but this has not happened in the past. |
12 |
|
13 |
I found somewhere the suggestion to add the following options to |
14 |
/etc/modprobe.d/sound.conf |
15 |
|
16 |
options snd-hda-intel vid=8086 pid=8ca0 snoop=0 |
17 |
|
18 |
The fading out/in *seems to be* less frequent since doing that. But |
19 |
that is my subjective feeling, not based on data. |
20 |
|
21 |
Any ideas on what might be wrong and how it can be fixed? |
