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

[Andrew Callan]

The Phoenix cME FirstBIOS Pro, Revision V146 1.00.01 on this machine has
very limited options in general.  There is not any option for
enabling/disabling the modem (or other devices such as NIC, wireless NIC,
sound, etc.).  So I guess I would assume that it is always enabled through
the BIOS?
