Subject: [PATCH] ALSA: hda - No loopback on ALC299 codec
Date: Tue, 16 May 2017 09:15:01 +0200 [thread overview]
Message-ID: <20170516071501.20787-1-tiwai@suse.de> (raw)
ALC299 has no loopback mixer, but the driver still tries to add a beep
control over the mixer NID which leads to the error at accessing it.
This patch fixes it by properly declaring mixer_nid=0 for this codec.
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195775
Fixes: 28f1f9b26cee ("ALSA: hda/realtek - Add new codec ID ALC299")
