This bug has been forgotten for a while, sorry for that.
Since the verbs are reverse-engineered and there is a significant risk
of breakage, we shouldn't apply it as default *yet*. So, instead, the

Hey, I tried the script solution together with the systemd service file.
It works very nicely!
I noticed that you also have to run the script when the device wakes from

For that to work, you have to add a few more targets to WantedBy (I just

Would there be by any chance a way to send that magic sequence through

That's great!
Here is the magic sequence of CORB commands needed to enable both
speakers. This is actually part of a much larger sequence that the
Windows driver does, but through trial and error, this is the minimum
required to make both speakers work.
