Digigram VXpocket440 on SuSE 10.1 - a lot of problems - few solutions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello!

[...]

1. distortions on high frequencies
When starting playback, almost every time(!), the sound is distorted, it
is rattling. It is really ugly. If the playback is paused for a few
seconds and started again, most times, the sound is fine afterwards.
Going back a few seconds can help, too.

-> /etc/modprobe.conf.local
options snd_vxpocket ibl=514

The option ibl is used for playback, too, as I could read in the source
code.


2. muting the pcm does not work properly
If playback is muted with alsamixer or kmix, often just one channel
(left or right) is muted or unmuted.

no solution

3. pcm volume control
Adjusting the volume sometimes leads to one missing channel or the
channels are differently loud.

no solution

4. machine hangup
After removing the card, the actual session is dead, which means:
keyboard doesn't work any more, but the mouse is working. It isn't
possible to switch to another console - even with the mouse. But it is
possible to login remote with another KDE-session e.g.

-> use the command pccardctl eject
When suspend to disk or ram is used, the card and the modules
snd_vxpocket, snd_vx_lib and snd_pcm must be unloaded before suspending.


5. fimrware?
vx-status reports, that the firmware would be loaded. I didn't start
vxloader. If I start it, I'm getting the message:

vxloader: no VX-compatible cards found

no solution

BTW, OpenSuSE 10.2 does have the same problems.


Hope it helps,
kind regards,
Andreas Hartmann
