Greetings,
I am writing to describe a problem I have involving
the snd-via82xx audio drivers on 2.6 kernels. I have updated to the
latest alsa-drivers to no avail.
Everything works fine, apart from one small
issue. Certain programs have strange clicks at certain points. The
main example is with fluidsynth http://www.nongnu.org/fluid/ When a note is turned off there is a very loud click
which can be louder than the note was - the same type of click that happens when
you turn a channel on or off.
This doesn't happen with any other sound card that
I have tried (tried a few others including snd-ice1712 on an m-audio delta
410). It also doesn't happen with the via binary oss style drivers,
"viaudiocombo" which are available from via's website.
The clicks do happen (suprisingly) in exactly
the same places with fluidsynth running into jack into snd-via82xx.
I have tried this on various different boards I have around, although they
are all types of VIA epia mini-itx boards.
I have also tried dxs_support=1,
dxs_support=2,dxs_support=3, dxs_support=4 and this doesn't help.
It may well be the same problem which was noted
here. https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1667
Its meant that I have to use the viaudiocombo
drivers for this purpose, and I'd rather use the nice up to date alsa
ones!
Please, I would be grateful for any help or
thoughts - I am an experienced coder, though I've never worked with device
drivers before,
Thanks,
