Good afternoon,

I picked up a Behringer UV1 for a review and ran into an odd error. ALSA, Pulse, and Jack all see the interface but there is an audio skip every second or so in the playback. Dmesg reported "clock source 41 is not valid, cannot use" and yeah, it does sound like a mismatched clock.

Since this is a new product it might be missing a config? I'm not sure how that works or who I should contact.

Hope someone can point me in the right direction.

Thank you,

Venn

P.S.

Included the output of dmesg and lsusb
