Subject: [PATCH] ALSA: usb-audio: disable 96khz support for HUAWEI USB-C HEADSET
Date: Tue, 10 Nov 2020 16:04:03 +0800 [thread overview]
Message-ID: <1604995443-30453-1-git-send-email-macpaul.lin@mediatek.com> (raw)
The HUAWEI USB-C headset (VID:0x12d1, PID:0x3a07) reported it supports
96khz. However there will be some random issue under 96khz.
Not sure if there is any alternate setting could be applied.
Hence 48khz is suggested to be applied at this moment.
