From fd28941cff1cd9d8ffa59fe11eb64148e09b6ed6 Mon Sep 17 00:00:00 2001 From: Jaroslav Kysela Date: Thu, 15 Dec 2022 16:30:37 +0100 Subject: ALSA: usb-audio: Add new quirk FIXED_RATE for JBL Quantum810 Wireless It seems that the firmware is broken and does not accept the UAC_EP_CS_ATTR_SAMPLE_RATE URB. There is only one rate (48000Hz) available in the descriptors for the output endpoint. Create a new quirk QUIRK_FLAG_FIXED_RATE to skip the rate setup when only one rate is available (fixed).
