Subject: [PATCH] hda: add eapd support to additional idt codecs
Date: Tue, 19 Jun 2007 10:27:25 -0400 [thread overview]
Message-ID: <4677E7CD.40209@embeddedalley.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 237 bytes --]
Added support for EAPD on the 927x, and 9227-8 IDT HDA codecs.
Enabling EAPD powers the internal speaker amp otherwise there is no
sound on systems with an internal amp.
