As I've reported several times to LKML, I'm experiencing annoying ALSA lockups
when using multimedia programs like xmms, xine, and mplayer.
My problem wasn't fixed in the last 4-5 kernels or so but I managed to figure
out a workaround. When booting with acpi=off, the lockups are gone.
Why?
Here's some info....
==========================================
ALSA errors with DEBUG on memory allocation, and verbose prink:
ALSA sound/core/pcm_lib.c:215: Unexpected hw_pointer value (stream = 0, delta:
-6488, max jitter = 8192): wrong interrupt acknowledge?
ALSA sound/pci/via82xx.c:687: invalid via82xx_cur_ptr, using last valid pointe
ALSA sound/core/pcm_native.c:1263: playback drain error (DMA or IRQ trouble?)
ALSA sound/pci/via82xx.c:687: invalid via82xx_cur_ptr, using last valid
pointer
mplayer:
ALSA lib pcm_hw.c:524:(snd_pcm_hw_drain) SNDRV_PCM_IOCTL_DRAIN failed:
Input/output error
alsa-pause: pcm drain error: Input/output error

Why does using ACPI cause my soundcard to lockup?
Any help will be greatly appreciated.
(BTW 2.4 kernels worked fine with ACPI on...)
