SubjectRE: [alsa-devel] ALSA:usb audio Higher sample rates on usb audio no longer working.
Date
Hi Con,

Thanks a lot for reporting the issue and also for taking your time to help me with lsusb output and dmesg logs.
I have sent a patch in another mail to fix this issue.
Could you help by checking if the patch fixes this issue for you?

Thanks,
Saranya
