Can you try 4.17.3 which is currently pending in bodhi? https://bodhi.fedoraproject.org/updates/FEDORA-2018-d92fde52d7 ? I pulled in a couple of fixes related to the media framework so it's worth testing to see if either of those fix your problem. Failing that, your best bet is to run a bisection.

Thanks, yes, 4.17.3 fixed the problem. Both sound and white balance are fixed for C525 and no dmesg errors.
Thanks for letting us know
