+Subject: ALSA: usb-audio: Add a quirk for Sonix HD USB Camera
+
+From: wangdicheng <wangdicheng@kylinos.cn>
+
+commit 21451dfd853e7d8e6e3fbd7ef1fbdb2f2ead12f5 upstream.
+
+Sonix HD USB Camera does not support reading the sample rate which leads
+to many lines of "cannot get freq at ep 0x84".
+This patch adds the USB ID to quirks.c and avoids those error messages.

+Subject: ALSA: usb-audio: Fix microphone sound on HD webcam.
+
+From: wangdicheng <wangdicheng@kylinos.cn>
+
+commit 74dba240881820b46b9b1c62ef4de3bfff47fbd4 upstream.
+
+I own an external usb Webcam, HD webcam, which had low mic volume and
+inconsistent sound quality. Video works as expected.

+The quirk_flags_table[] is sorted in the USB ID order, while the last
