Subject: [alsa-devel] Bug report for changes in ucm2 with chtrt5645 card on Lenovo Miix 320
Date: Fri, 10 Jan 2020 11:25:43 +0100	[thread overview]
Message-ID: <20200110102543.GA1689@impa> (raw)

Hi alsa devs,

I'm on Arch Linux on a rather uncommon laptop (Lenovo Miix 320) and my sound
stopped working on the upgrade from alsa-lib 1.1.9 to 1.2.1. wabbits on
IRC helped me track down the problem to a change in the
/usr/share/alsa/ucm (now /usr/share/alsa/ucm2) files. It seems like
/usr/share/alsa/ucm2/chtrt5645/HiFi-dmic2.conf and a symlink at
/usr/share/alsa/ucm2/chtrt5645/LENOVO-80XF-LenovoMIIX320_10ICR-LNVNB161216.conf
were specifically added for this laptop but in the contrary they break the
sound for me.

After the upgrade to alsa-lib 1.2.1 the sound is not working. The commands play no sound:

    pasuspender -- speaker-test --nloops=1 --channels=2 --test=wav --device=hw:0,0
    pasuspender -- speaker-test --nloops=1 --channels=2 --test=wav --device=hw:0,1

And this is the alsa-info.sh output http://alsa-project.org/db/?f=f883910a5c5101b4b1ea4202d1fe84ccd139f796

After deleting the /usr/share/alsa/ucm2/chtrt5645/LENOVO-80XF-LenovoMIIX320_10ICR-LNVNB161216.conf
symlink both commands from above play sound and this is the alsa-info.sh
output http://alsa-project.org/db/?f=e759eb9118a191b6c3b8c021fed58abc9cf95076

Thanks.

- Tim
