ChangeSet 1.2181.25.31, 2005/03/22 09:15:23+01:00, [EMAIL PROTECTED]
[ALSA] use amp capabilities from afg if amp override not set
HDA Codec driver
Fix by Matt <[EMAIL PROTECTED]>:
Some HDA codec nodes contain an amp, but do not provide local amp
capabilities. In these cases, AC_WCAP_AMP_OVRD is not set so we
should query the AFG nid in order to get the general amp capabilities.
