From 4fe2ca14678174d9df254ae3ba2b79bacc19e2ee Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 14 Jan 2011 10:33:26 +0100 Subject: [PATCH] ALSA: hda - More coverage for odd-number channels elimination for HDMI The commit ad09fc9d2156f3d37537b34418a6b79309013d33 didn't cover the case for Intel and Nvidia HDMIs, where hdmi_pcm_open() is called. Put the hw_constraint there, too.
