Subject: [PATCH] ALSA: hda/tas2781: select program 0, conf 0 by default
Date: Fri, 15 Dec 2023 00:33:27 +0100
Message-ID: <038add0bdca1f979cc7abcce8f24cbcd3544084b.1702596646.git.soyer@irl.hu>

Currently, cur_prog/cur_conf remains at the default value (-1), while
program 0 has been loaded into the amplifiers.

In the playback hook, tasdevice_tuning_switch tries to restore the
cur_prog/cur_conf. In the runtime_resume/system_resume,
tasdevice_prmg_load tries to load the cur_prog as well.

Set cur_prog and cur_conf to 0 if available in the firmware.
