Hi,
I'm not sure whether or not this is a kernel problem. I get the
following log messages sometimes when I play sounds on my ultra5. This
happens quite sporadically, so it is a bit difficult to reproduce. I
use ogg123 combined with esddsp to play sounds. My kernel is
linux-2.6.16.14.
Does anyone have suggestions to how I can investigate this problem
further?
Regards,
Erik Østlyngen

I think I once had a similar problem on an ultrasparc 2 after I adapted
the sound of the 2.6 kernel to support sbus. I remember it only
appeared when I was playing using alsa and not when using the OSS
interface. Further I think I debugged it as far that I could tell that
the bug is in alsa code and not sparc or sbus specific.
But this was some time ago (2.6.12 or so) and I gave my sparc away
since then.
Maybe you could search the mailing list archives for the sparclinux
list from September/October 2005:

Subject: patch for CS4231 on sbus

Hi,
This patch enables SBus support for the cs4231 sound driver.
It is tested on an Ultra2. Capture and playback both work.
I experienced lags and crashes using certain threaded
players like ogg123 and mp3blaster, while the former is
lagging far more. This behavior may be specific to SMP
systems. It is reproducable using the dummy sound card
driver. Sox works flawlessly.
It is not tested on EBus at all.
Setting up the calculation of ptr in snd_cs4231_playback_pointer
was a bit strange. I got it to work by not incrementing the
[pc]_periods_sent counter when starting DMA the first time
in cs4231_dma_trigger. Therefore this dummy thing.
