Subject: RE: [alsa-devel] ALSA:usb audio Higher sample rates on usb audio no
longer working.
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
