Hi there,
I am trying to have a not too bad audio experience on my laptop,
which has a i8x0 audio chipset (snip). I have a 2.6.6-rc2 kernel,
preempt enable, without any patches, but with the Jack o Quinn realtime
module. I happened to use 3 different players on my former PC: rythmbox,
alsaplayer and xmms. But on my laptop, whenever I am doing cpu-intensive
or heavy disk related operations, there are big audio drops which are
quite annoying. Here is my configuration:
- rhythmbox: I don't do anything special to gstreamer, I think it
uses oss emulation. Totally unusable on my laptop :( drops, really bad
sound, gstreamer seems to have some nasty bugs. When I am doing
somehting like 'gst-launch sinesrc ! osssink', it doesn't sound like a
sine at all !
- xmms: with alsa plugin, it works, but it 'stops' working for a few
seconds when I am doing CPU and/or disk intensive operations ( example:
tar -xjf kernel-sources ). I've never managed to make the jack plugin work.
- alsaplayer with jack output plugin, jack launched with the -R
option. Jack doesn't complain about xruns, but still, alsaplayer still
stops, like xmms under the same conditions (the time counter stops for
around a second).
I was so desperate that I thought about a hardware problem in my
audio chipset, but it works perfectly on windows (re snip).
What should I do to avoid these really annoying audio drops under
linux ?
Thank you,
David
