Hello all,
A friend of mine, who is mainly a Windows user and has limited knowledge of
Linux, has two HP laptops running Archlinux.
One of them works perfectly with an RME Octamic-XTC. The other doesn't
seem to detect it as a sound card (it doesn't show up in aplay -l).
On both the RME is recognised as an USB device (by lsusb).
I'm trying to help him fix this (remotely). We compared kernel and alsa
versions, they are the same. In fact the two Linux installations should
be identical, both had a full update before I shipped to two laptops
to him.
What could be the problem on the second PC ?
I have an HP Z2 Tower G4 Workstation for my music and a Soundcraft Signature 12
MTK as my main interface. Oddly enough, I had almost the same problem when I
switched workstation from Dell to HP in early 2020. The first time I installed
my distro (ubuntustudio), MTK was not recognized. I tested with lsusb and there
was the interface but not in alsa -l. I stumbled on the thread below and tried
with qjackctl and then it worked. No idea why that happened. After a power
outage a few months ago, the same thing happened. I did the same thing and ran
qjackctl and then it works again, both restarting and pulling out and in the
interface. Inexplicable but maybe a workaround.
