repeated reboot change audio sound cards

In the zynthian.local web interface, changing the HARDWARE > Audio > Soundcard setting to any other option and then rebooting results in repeated reboots. It only stops when I change it back to Rbpi Headphones. Therefore, I’m unable to use other sound cards listed, such as the M-Audio M-Track Plus 2 or Steinberg Ur22 Mkii. What should I do?

Hi @798714773! Welcome to the community.

The soundcard settings are important as Zynthian depends on a working jackd which is the module that uses these settings. You must have the right settings set for the attached sound card at boot time, i.e. if you want to use Steinberg UR22 you must select that from webconf and attach the soundcard then reboot. Is this what you are doing?
