Greetings,

I am writing to describe a problem I = have involving=20 the snd-via82xx audio drivers on 2.6 kernels. I have updated = to the=20 latest alsa-drivers to no avail.

Everything works fine, apart from one = small=20 issue. Certain programs have strange clicks at certain = points. The=20 main example is with fluidsynth http://www.nongnu.org/fluid/ When a note is turned off there is a very = loud click=20 which can be louder than the note was - the same type of click that = happens when=20 you turn a channel on or off.

This doesn't happen with any other = sound card that=20 I have tried (tried a few others including snd-ice1712 on an = m-audio delta=20 410). It also doesn't happen with the via binary oss style = drivers, =20 "viaudiocombo" which are available from via's website.

The clicks do happen (suprisingly) = in exactly=20 the same places with fluidsynth running into jack into = snd-via82xx.

I have tried this on various different boards I have around, = although they=20 are all types of VIA epia mini-itx boards.

I have also tried dxs_support=3D1,=20 dxs_support=3D2,dxs_support=3D3, dxs_support=3D4 and this doesn't = help.

It may well be the same problem which = was noted=20 here. ht= tps://bugtrack.alsa-project.org/alsa-bug/view.php?id=3D1667

Its meant that I have to use the = viaudiocombo=20 drivers for this purpose, and I'd rather use the nice up to date alsa=20 ones!

Please, I would be grateful for any = help or=20 thoughts - I am an experienced coder, though I've never worked with = device=20 drivers before,

Thanks,
