[alsa-devel] Alsa 1.0.13 (and others) does not work on ALC880

[Andrew Callan]

I tried probe_mask=3.  aplay -l shows the Si3054 Modem device again.
Sound does not work.  So I guess this points to the modem rather than the
probing.  It looks like Eric has the same modem as I do; the Vendor Id,
Subsystem Id, and Revision Id all match.
