[PATCH 3.12 14/60] ALSA: hda - fix Lewisburg audio issue

From: Jiri Slaby
Date: Tue Mar 14 2017 - 09:33:24 EST


From: Jaroslav Kysela <perex@xxxxxxxx>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit e7480b34ad1ab84a63540b2c884cb92c0764ab74 upstream.

Like for Sunrise Point, the total stream number of Lewisburg's
input and output stream exceeds 15 (GCAP is 0x9701), which will
cause some streams do not work because of the overflow on
SDxCTL.STRM field if using the legacy stream tag allocation method.

Fixes: 5cf92c8b3dc5 ("ALSA: hda - Add Intel Lewisburg device IDs Audio")
