From a6f2fd557f993aecc93d51afd9e339524107937f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 28 Feb 2012 11:58:40 +0100 Subject: ALSA: hda - Add position_fix=4 (COMBO) option This patch adds a new position_fix option value, 4, as a combo mode to use LPIB for playbacks and POSBUF for captures. It's the way recommended by Intel hardware guys.
