Hi all,
as the subject says my sound card stopped working after the update to
F24. The sound card worked like a charm in F22 and F23.
Now the situation is as following:
After booting the card is NOT listed by lsusb, yet the LED auf the 2i2
is on. After replugging the device it is listed by lsusb:
Bus 001 Device 011: ID 1235:8016 Focusrite-Novation
Now it gets wierd. As long as I do NOT log into a desktop session the
card works fine in the console and is listed by lsusb. The card is
selected in alsamixer and aplay works as expected. The card works
and audio files can be played.
As soon as I log in to a desktop session (standard GNOME in my case)
the sound card doesn't work. Seems to be some kind of a pulseaudio
problem. It is still selected in alsamixer, but not available in pacmd
