[PATCH] ALSA: usb-audio: Add FIXED_RATE quirk for JBL Quantum650 Wireless
From: Daniel C. Ribeiro
Date: Sun Jul 19 2026 - 05:00:53 EST
JBL Quantum650 Wireless (0ecb:2125) requires the same workaround that
was used for JBL Quantum610 and Quantum810 for limiting the sample rate.
Without it, the capture (microphone) stream fails to work. Setting the
QUIRK_FLAG_FIXED_RATE flag, as done for the sibling models, makes both
playback and capture work correctly.
