Subject: No HDA sound output with AMD IOMMU on master
Date: Thu, 04 Nov 2021 12:01:51 -0400 [thread overview]
Message-ID: <1636040759.fnw68jgcw1.none@localhost> (raw)
In-Reply-To: 1636040759.fnw68jgcw1.none.ref@localhost
Hi,
At some point between 86f925fded03 and 5f4e450cd96b, the built-in sound
card on my ASRock B450 Pro4 has stopped working for me. All controls are
unchanged (no new or removed controls, all outputs are unmuted), but
when I try to play sound, I hear a click from the output powering up but
no sound otherwise. While attempting to play sound, the following lines
are output to the kernel log:

Note that I first attempted to play audio around 15 seconds in, then
tried again about 730 seconds later.
Adding mem_encrypt=off to the kernel command line does not fix the
issue, but adding mem_encrypt=off amd_iommu=off to the kernel command
line does fix it. I am not using any other IOMMU-related parameters such
as iommu=pt.
I have not yet tested it, but it seems reasonable that this issue is
probably related to the recently pulled "ALSA: memalloc" series of
changes.
Let me know what further information or testing is required. I can do a
full bisection but it is somewhat time-consuming due to the manual
nature of the tests.
Thanks,
Alex.
