 Posted: Fri Jul 08, 2005 4:52 am Post subject: [SOLVED] Sound Skips (ALSA) |
 |
|
| Code: | insomnia vitaliy # lspci -v | grep -i audio
0000:00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 Audio (rev 04) |
I am having some problems with my sound, I have everything configured and everything appeared to be normal. The only problem I had then was I did not have multiplexing sound and the following has fixed it.
| Code: | insomnia vitaliy # cat /home/vitaliy/.asoundrc
pcm.nforce-hw {
type hw
card 0
}
pcm.!default {
type plug
slave.pcm "nforce"
}
pcm.nforce {
type dmix
ipc_key 1234
ipc_perm 0660
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 4096
#rate 44100
rate 48000
}
}
ctl.nforce-hw {
type hw
card 0
} |
Everything works just fine now and got multiplexing sound working. The only thing is the sound skips whenever I am using my browser for example and click back button it would skip for a second. Or for example when I would click different news story in Lifera (GTK2 RSS reader) the sound would skip with every click. Just skips whenever I am using different applications.
Any idea what is causing this and how do I fix this?

This problem has been reported many places in the forums.
If you have a slower processor or a lot of programs running, the software mixer can miss filling the audio buffer and cause skips. What I did to fix it on my P4M-2.4 was install a more efficient kernel. I'm running 2.6.13-mm1 (mm-sources) right now and I don't have the problem. (I got skips because my cpu throttles to 1.2 G when not busy). Apparently Firefox eats CPU cycles.
Search the forums, I've been out of the loop for a while, there may be better fixes out there. I've heard that a newer version of alsa with some optimization should make this problem go away for some...
For future reference it would help to post your kernel version, alsa version and system specs...

| The box is Pentium 4 2GHz with 512MBram running 2.6.11-gentoo-r11 kernel (alsa is built into the kernel). |

simply follow gentoo alsa guide |

Well I just recompiled my kernel and removed ALSA, then used alsa-driver. I must say that it did get better but it still manages to skip when I have some load (we are not talking about me compiling three different things at the same time but something as basic as having 3 tabs open in Firefox and clicking links).
Any more ideas? This is simply ridiculous. |

Don't want to change kernels?
Actually I only got skips when I was merging, browsing and playing music... I think it was a threading priority thing... Not that I know anything about such things.
Have you tried increasing the buffer size in .asoundrc (or /etc/asound.conf)?

Did not really want to switch the kernel and would like to stick to stable Gentoo releases. I have tried increasing the buffer size and that has fixed it. Thank you so much, this was so minor and was bothering the living hell out of me! |
