Subject: [PATCH] ALSA: hda_intel: apply the Seperate stream_tag for Sunrise Point
Date: Thu, 26 Mar 2015 13:28:39 +0800	[thread overview]
Message-ID: <1427347719-121305-1-git-send-email-libin.yang@intel.com> (raw)

From: Libin Yang <libin.yang@intel.com>

The total stream number of Sunrise Point's input and output stream
exceeds 15, which will cause some streams do not work because
of the overflow on SDxCTL.STRM field if using the legacy
stream tag allocation method.

This patch uses the new stream tag allocation method by add
the flag AZX_DCAPS_SEPARATE_STREAM_TAG for Skylake platform.
