Subject: [PATCH] ALSA: usb-audio: Add delay quirk for HIK camera
Date: Thu, 29 Oct 2026 11:28:56 +0800 [thread overview]
Message-ID: <20261029032856.7100-1-ki.chiang65@gmail.com> (raw)
Audio control requests that set the volume sometimes time out on the
HIK 1080P Camera (2bdf:0280).
Adding a 1ms delay between control messages avoids the issue. Apply
QUIRK_FLAG_CTL_MSG_DELAY_1M for this device.
