Subject: Add route_policy copy to HDA-Intel.conf for capture
X-Git-Tag: v1.0.20~2
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=59c774ed5ee00e9623a204c3234191d6a6d8cf7a;p=alsa-lib.git

Add route_policy copy to HDA-Intel.conf for capture

Since some digital mics have the phase-inversion problem in one channel,
adding both channels for mono stream results in the noise.
Use route_policy copy to avoid that situation.
