Package: linux-image-6.12.57+deb13-amd64 Version: 6.12.57-1 "aplay -l" shows only "card 0". To fix it you have to rebuild the kernel with "CONFIG_SPI_AMD=m". Then "aplay -l" will also show "card 1". This is for old steamdeck, not OLED version. To find the parameter, I was rebuilding the kernel with downloading v6.12.48 from kernel.org, "cp /boot/config-6.12.48+deb13-amd64 .config" and "make oldconfig", I hope it's still valid.
