[Bug 677709] Re: [Realtek ALC269] Playback problem on Asus ul30a
I've spent a while over the last couple of weeks searching around for information on any latency issues with the notebook, but unfortunately had no luck. It's running the latest firmware available. That said, the audio works perfectly under 10.04, which would tend to rule out firmware issues.

[Bug 677709] Re: [Realtek ALC269] Playback problem on Asus ul30a
Ok - for a bit of clarification, I see these problems mostly when I'm just using pulseaudio as a normal user, playing back sound on my laptop through the laptop's inbuilt speakers (or headphones). So the source the sink are the same machine. However - I also see them pop up when I use my laptop as a source, and the desktop pc as a sink. The desktop pc has no problems whatsoever playing back audio locally. This leads me to believe the problem is caused somewhere in the 'source' side on my laptop. Pulseaudio's daemon.conf is back to it's default settings now, but the values I've tried modifying are: default-fragments = 8 default-fragment-size-msec = 10 I changed these two settings in a whole range of combinations with values ranging from 2 up to 30. I tried pretty much every combination possible, with equal values, one high and the other low, and the opposite. Some settings made the problem worse, but no combinations made the glitches less frequent than the default 8/10 values. resample-method = speex-float-1 I tried changing this one to src-sinc-fastest to see if it was a processing power problem (i gather src-sinc-fastest is the least demanding method), but there was no noticeable change. -- [Realtek ALC269] Playback problem on Asus ul30a https://bugs.launchpad.net/bugs/677709 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 677709] Re: [Realtek ALC269] Playback problem on Asus ul30a
Thanks for the clarification, which seems to imply there is a scheduling and/or hardware issue at the root of things. The fact that completely different hardware as your other source sink coupling seems to work fine corroborates that observation. At this point I'm unsure whether we can really chalk this up to an audio stack issue. Have you investigated whether there are firmware updates or pci latency tunings that can be applied? -- [Realtek ALC269] Playback problem on Asus ul30a https://bugs.launchpad.net/bugs/677709 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I need to know what daemon.conf settings you've modified, and what the results were.

I've now tried a whole stack of combinations of values for those settings, and while some values made the problem noticeably worse, none of them fixed the playback issues.

It's currently set to: resample-method = speex-float-1 default-fragments = 8 default-fragment-size-msec = 10 I believe they're the default settings.
