From 36ac4ad3d054a7b4962a6393630a73591cfa9558 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Tue, 25 Oct 2011 16:53:00 +0200 Subject: hda: do not mix output and input streams, RHBZ #740493 Windows 7 may use the same stream number for input and output. That will result in lot of garbage on playback. The hardcoded value of 4 needs to be in sync with GCAP streams description and IN/OUT registers. Signed-off-by: Marc-Andr?
