Bug#990106: Switching on/off 5.1 audio amplifier/receiver causes graphics card to turn off
Package: linux-image-5.10.0-7-amd64
Version: 5.10.40-1
I have a 5.1 audio amplifier/receiver connected to a Gigabyte X570 AORUS PRO (Realtek ALC1220) via SPDIF.
After updating from 5.10.0-6-amd64 to 5.10.0-7-amd64, the AMD Vega 56 graphics card turns off as soon as I switch the amplifier on or off.
The first time I encountered the issue was when shutting down Debian, leading me to suspect it was either a race condition that was never triggered before or an electricity spike.
That turned out not to be the case, because I can reliably reproduce the issue and I confirmed that it doesn't happen in 5.10.0-6-amd64.
Once the graphics card is turned off the computer seems to remain responsive and SysRq commands work.
