[M7X0SU, Realtek ALC662 rev1, Black Headphone Out, Rear (Any output, actually)] Underruns, dropouts or crackling sound

[André Carvalho]

There have been multiple reports of such problems, such as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/381201 , and they relate to power saving being on that causes the problem. However, even with those off, it keeps happening.

On 12.04.1 it was fine until I did a system update, and on 13.10 (it was suggested to me that I should see if the problem was fixed), the problem was there immediately out of the box (although it wasn't there when I was on a live session).

The test sounds came out fine, but when I play back a music file through (for example) Totem, it eventually starts crackling and popping. I tested the song in the "Examples" folder and some mp3's in 12.04.1, but I didn't test any mp3's yet on 13.10.

I should add that it is not all the time.

For this song, http://www.youtube.com/watch?v=q2i6DNgHcrM , which I use because of the lack of beats in it, I got problems for 15s, then it was fine for another 15s or so, then it came back, then it went away, until 3 minutes into the song, the problem came back... and it's still going (I'm playing the song on loop)

So far, with (today?)'s update (pulseaudio 1.3), everything's been much better. Only under heavy system loads has this been a problem.

[André Carvalho (andrecarvalhopt)]

Except the problem came back. Still, it was good for 20 minutes or so.
