I’m using pulseaudio and recently got the Focusrite Scarlett 2i2 2ng gen USB audio interface.
After connecting, input and output seem to work fine, but after playing some music with rhythmbox (or vlc, Firefox…), the sound stops right when the song changes (or randomly after some time), while the player still indicates the next song playing and I can’t get it working again without disconnecting and connecting again. E.g. when I change to a different USB sound card, the sound comes back, but changing back to the 2i2 makes it mute again.
dmesg doesn’t show anything during the whole period instead of “new high-speed USB…”. To me, there is no indication in the system that anything changed, but I can’t hear the output anymore. The direct monitoring still works though, because it’s implemented in the hardware.
I have KXStudio in dualboot (using jack) and there it works perfectly.
Any ideas how to debug this problem any further?
