Around line 1350 in ac97_codec.c:
/* build surround controls */
if ((snd_ac97_try_volume_mix(ac97, AC97_SURROUND_MASTER))
&& !(ac97->flags & AC97_AD_MULTI)) {
/* Surround Master (0x38) is with stereo mutes */
if ((err = snd_ac97_cmix_new_stereo(card, "Surround Playback",
AC97_SURROUND_MASTER, 1, 0,
ac97)) < 0)
return err;
}
