HDAjackRetask: tee: /sys/class/sound/hwC1D0/reconfig: No such device

Question

I am trying to reconfigure the setup of my microphone with HDAjackRetask however when I click reply I get the message:

tee: /sys/class/sound/hwC1D0/reconfig: No such device

Here is a screenshot:

I am running Deepin 15.1 desktop. Thanks in advance!

Solution

If you follow hdajackretask source, you can see it creates nothing else than a script in temp folder and run it with root privileges. I'd suggest to start from that; errors.log may have some additional clue.

And then: does reconfig file exist in the first place? Because it's not even created if kernel hasn't been compiled with CONFIG_SND_HDA_RECONFIG option.

Last if this still hasn't told you nothing, you might consider to enable tracepoints. For as much as I can't see a rationale, sending raw commands is the last possible thing.

They can be eventually interpreted with hda-decode-verb contained in hda-emu:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-emu.git
autoreconf -i
./configure --with-kerneldir=/path/linux-2.0
make install
