Subject: [PATCH 3.13.y-ckt 22/30] ALSA: usb-audio: Fix TEAC UD-501/UD-503/NT-503 usb delay
Date: Wed, 10 Feb 2016 13:42:00 -0800	[thread overview]
Message-ID: <1455140528-17076-23-git-send-email-kamal@canonical.com> (raw)
In-Reply-To: <1455140528-17076-1-git-send-email-kamal@canonical.com>

3.13.11-ckt35 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Guillaume Fougnies <guillaume@eulerian.com>

commit 5a4ff9ec8d6edd2ab1cfe8ce6a080d6e57cbea9a upstream.

TEAC UD-501/UD-503/NT-503 fail to switch properly between different
rate/format. Similar to 'Playback Design', this patch corrects the
invalid clock source error for TEAC products and avoids complete
freeze of the usb interface of 503 series.
