Hello Clemens, I tried the new quirk, but no success. The lsusb -v gives the same output as before. When I use alsamixer, I have no controls. At least the card is mentioned in /proc/asound. Which steps should be next to bring the card to life? Best regards, Ewald On 26/07/12 20:37, Clemens Ladisch wrote: > Ewald Reisenberger wrote: >> the Roland UA-55 is not recognized by Alsa.
