From b0bb3aa6233dccfccd040793d0d9ce838e4890e1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 3 Jul 2009 23:25:37 +0200 Subject: [PATCH 1/1] ALSA: hda - Don't override maxbps for FLOAT sharing with linear formats When FLOAT PCM format is available but together with other linear PCM formats, don't override maxbps value. For FLOAT format, it's always 32, thus it can be better checked in snd_hda_calc_stream_format(). Otherwise the maxbps 32 might be used wrongly even if the linear PCM doesn't support it.
