Hello!

dmesg:

3.13 killed what was left of my audio support on the panda-es *tears*

Comment 1 Takashi Iwai 2013-12-04 13:42:49 UTC 
Is this a regression in 3.13 kernel, and it worked with 3.12 kernel?
Comment 2 Tobias Jakobi 2013-12-04 14:08:11 UTC 
Yes, you probably remember this one here:
https://bugzilla.kernel.org/show_bug.cgi?id=64741

So, on 3.12 at least the 96kHz rate worked.
Comment 3 Takashi Iwai 2013-12-13 11:57:53 UTC 
The upstream patch below should fix the issue.  It's found in linux-next, and will be merged to Linus tree later.

Fix patch
Comment 5 Tobias Jakobi 2013-12-14 13:59:23 UTC 
Can verify that the applying the patch lets the device appear again.
