From f56742cc41895b1ed3742406dc3587b0d6424acb Mon Sep 17 00:00:00 2001 From: Andrej Krutak Date: Sun, 18 Sep 2016 20:59:25 +0200 Subject: ALSA: line6: Add LINE6_CAP_IN_NEEDS_OUT, a void playback stream during capture E.g. POD X3 seems to require playback data to be sent to it to generate capture data. Otherwise the device stalls and doesn't send any more capture data until it's reset.
