Hi everybody!
I'm one of those (unlucky) owners of a via8233 chip. I'm using
alsa-0.9.6 with a 2.4.21 kernel. The sound playback is (you'll
guess it) noisy, unless I use that dxs_support=3 options with
snd-via82xx. This is not a problem, but I observe other strange
behaviours.
(1) Very often, ALSA puts an error message in my syslog, and it
gets repeated a *lot*. (Every couple of seconds.)
Sep 1 12:00:20 bender kernel: ALSA ../alsa-kernel/pci/via82xx.c:687:
invalid via82xx_cur_ptr, using last valid pointer
Sep 1 12:00:41 bender last message repeated 7 times
Sep 1 12:01:44 bender last message repeated 18 times
Sep 1 12:02:40 bender last message repeated 14 times
Sep 1 12:03:58 bender last message repeated 2 times
This was copied from the syslog, while mp3blaster was playing.
The error appears very often, when using mp3blaster and less
often, when using xmms. Also, there is a click in the sound,
when the error comes. The errors shows up with both,
dxs_support=0 and dxs_support=3.
Is this message normal, or is there something wrong? Has
anybody else having this message?
(2) I often have observe mp3blaster displaying `Sound device
control error.' and then immediately skipping to the next
song. This is REPRODUCABLE! This always happens at the same
positions in songs! For example, I always get this in the
23rd second of one of my mp3's. This is very annoying. xmms
does not have this problem. (dxs_support=[0|3] does not
matter here.)
(3) As I already reported earlier, xmms has a sporadically noisy
playback, which appears only, when using dxs_support=3. (with
dxs_support=0, it is noisy all the time, but it's not the same
noise.)
(4) xmms sometimes fails to skip to the next song, at the very end
of the current song. It just blocks. It does not do so, with
dxs_support=0, only with dxs_support=3. Note: My xmms uses
the OSS interface, not the ALSA plugin, because it makes xmms
crash.
