choppy sound

English Multimedia
#1

My sound was working fine except I couldn’t get system sounds (notifications) to work. So I decided to install pulseaudio to see if it would fix it. Now I get system sounds and my other sounds, but now in most things (such as firefox and warcraft 3) the sound is choppy.

I’ve tried SDB:AudioTroubleshooting - openSUSE and a couple other things I’ve googled but it’s not working for me. I’d like to be able to fix it or at least go back to the way it was.(I can live without system sounds)

Thanks in advance.

There are a number of suggestions in that step-7. Can you be more precise as to which of the suggestions you tried? Without specifics, its likely not possible to offer any help, except to say try all of the suggestions in step 7 again, and advise which ones you tried, what errors you get, etc … Also, are you using gnome or kde ?

#3

I’m running kde. I tried the part "A possible fix to choppy / skipping sound " part. I looked at the 3 links, but I couldn’t see anything that seemed like it would help me.

The other thing I did was change the default-sample-rate in the daemon.conf from 41400 to 48000.

Why did you stop there?

Since you added extra pulse files (presumeably when you enabled pulse) to you have an /etc/pulse/default.pa file?

Also, did you try this from one of those links: PulseAudio - openSUSE

**Glitches in audio playback
**
Edit /etc/pulse/daemon.conf: uncomment the default-fragments and default-fragment-size-msec, and change values from the default 4 and 25 to 16 and 21.

Please report back in bug 381686 if this works or not for you.

Did you report back in the bug ?

#5

I do have a default.pa file. I’m not sure what you mean by reporting in the bug.

I downloaded a pulse volume setting thing and turned down the volume while turning up my speakers. This seems to have gotten rid of the choppy sound.

#6

If your PC has a default.pa, did you try the suggestion in the troubleshooting guide?

That suggestion was to try to turn timer-based scheduling off, and do this by replacing the line

 load-module module-hal-detect

by in /etc/pulse/default.pa by

 load-module module-hal-detect tsched=0

you will likely need to restart your alsa driver (easiest for me to tell you to restart your PC) to check if this works.

The comment about reporting in the bug report, is associated with this pulse audio glitch removal suggestion:

Glitches in audio playback

Edit /etc/pulse/daemon.conf: uncomment the default-fragments and default-fragment-size-msec, and change values from the default 4 and 25 to 16 and 21.

Please report back in bug 391686 if this works or not for you.

ie if that fix does not work, the authors of that wiki asked you provide input into the bug report .

I’m glad to read you found a solution!

… but I have no idea what a “pulse volume setting thing” is. It might help others reading this thead if you could be more precise than a “pulse volume setting thing” :\
