[alsa-devel] [PATCH 002/003] snd-powermac: AWACS and Screamer mixers for PM7500, Beige, and iMac SL

Risto Suominen risto.suominen at gmail.com
Mon Apr 14 19:12:44 CEST 2008


From: Risto Suominen <Risto.Suominen at gmail.com>

Add mixer controls and correct headphone detection bits for PowerMacs
7300/7500 (AWACS) and G3 Beige (Screamer), and iMac G3 Slot-loading
(Screamer).
