Takashi Sakamoto a4ce4337dc ALSA: oxfw: fix functional regression for Mackie Onyx 1640i in v5.14 or later ... [ Upstream commit cddcd5472a ] A user reports functional regression for Mackie Onyx 1640i that the device generates slow sound with ALSA oxfw driver which supports media clock recovery. Although the device is based on OXFW971 ASIC, it does not transfer isochronous packet with own event frequency as expected. The device seems to adjust event frequency according to events in received isochronous packets in the beginning of packet streaming. This is unknown quirk. This commit fixes the regression to turn the recovery off in driver side. As a result, nominal frequency is used in duplex packet streaming between device and driver. For stability of sampling rate in events of transferred isochronous packet, 4,000 isochronous packets are skipped in the beginning of packet streaming.
