I'd try somethng like amixer -c <card #> contents > somefile.txt And then examine somefile.txt carefully. There may be an enable/disable logical switch that nothing else picks up. Because SPDIF isn't that popular it may default to off. I have a Pinebook Pro laptop and without proper software the speakers don't turn off when you plug headphones in, and alsamixer doesn't help. amixer shows umid=28,iface=MIXER,name='Speaker Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on And sure enough I can turn it off with this script: #!/bin/bash # Turn laptop speakers (always card 0) off amixer -c0 cset numid=28 0 or back on with amixer -c0 cset numid=28 on You have to give cset the whole numid=nn to identify the control uniquely. There's a man page of course. amixer on Debian is in alsa-utils On 4/29/21, Ralf Mardorf <ralf.mardorf@xxxxxxxxxxxxx> wrote: > On Thu, 29 Apr 2021 12:25:54 -0400, Mary Strimel wrote: >>I have a new Asus Xonar SE card that I have just installed.
