No

I have a system that worked fine with the closed-source au8830
driver. I recently upgraded it to kernel 2.6.7 and have been
trying to get sound working again, without luck. The module
loads correctly, the card appears in /proc/asound, and programs
that access the sound card -- for instance, XMMS -- work fine.
The only problem is that no sound comes out of the speakers!
It's almost as if everything is muted, but the mixer settings are
maxed out (at least, the main volume and PCM are, as well as
anything else that looked vaguely like a playback channel),
and

dmesg doesn't show any errors, just the initialization message
from the driver:
Vortex: init.... <6>done.

/proc/asound/cards says:
0 [au8830 ]: Aureal Vortex - au8830
au8830 at 0xe8040000 irq 10

    Is this really 2.6.7, or is it a later BK snapshot? I
    needed to make a change between 2.6.8-rc2 and 2.6.8-rc4.
    Linus's f_pos / lseek changes caused writing to the mixer to
    return -ESPIPE.

    Yes, it's really 2.6.7. Also, unless the mixer programs are
    suppressing errors, I don't think it could be the problem
    you suggest: everything that accesses the audio devices
    works as usual, I just don't get any sound coming out of the
    speakers.
