There're several different actual hardwares sold by Huawei, using the same USB ID 12d1:3a07.
The first one we found, having a volume control named "Headset Playback Volume", reports a min value -15360, and will mute iff setting it to -15360. It can be simply fixed by quirk flag MIXER_PLAYBACK_MIN_MUTE, which we have already submitted previously.[1]
The second one we found today, having a volume control named "PCM Playback Volume", reports its min -11520 and res 256, and will mute when less than -11008. Because of the already existing quirk flag, we can just set its min to -11264, and the new minimum value will still not be available to userspace, so that userspace's minimum will be the correct -11008.
