Hi,
I see that on 2.6.18-ck1 still some sort of quirks patch is needed for
VIA chips.
I get plenty:
ALSA: underrun, at least 0ms.
and with 2.6.17-ck1 with the quirks.c.patch I did not. But the patch
does not fit on 2.6.18 :-(
Strangely enough this time around I do *not* get underruns on vt's with
mpg321 and I *do* get them on X. Last time around it was the reverse.
Is there a fix for 2.6.18 ?
Thanks!

Slight correction: I get underruns on X *and* vt's using the snd-via82xx
card (builtin) and *not* using the snd_ca0106 (PCI SB live).

Ah, right, that stuff.
IIRC that VIA on-board off-board on-again thing has still been rearing
its ugly head after 2.6.17, with a longish recent discussion on LKML
(~3 weeks ago?) where people were annoyed that it still had so many different
ways of breaking no matter how hard you tried to find a generic mechanism
that successfully applies to all devices out there.
As such I'm not surprised in the least that it's still not working for you.
Of course I don't know the thread by heart right now, but if you don't
manage to find it, then I'll try to dig it up.

My most recent patch solves all the known issues to my knowledge.
However, it is written with very little understanding of the reasons
behind the quirk. Alan Cox posted some info but having just started a
real job I haven't had time to go into this stuff in detail.
I think Greg has queued this patch for 2.6.19 but wouldn't be surprised
if people object to it...
