From: Christopher Swenson swenson@swenson.io Date: Sun, 14 Jun 2020 15:19:41 -0700 Subject: [PATCH] ALSA: usb-audio: Set 48 kHz rate for Rodecaster

Like the Line6 devices, the Rode Rodecaster Pro does not support UAC2_CS_RANGE and only supports a sample rate of 48 kHz.

Tested against a Rode Rodecaster Pro.
