stable inclusion from stable-v5.10.109 commit cbd27127af5f859929d707748633f47e08b3b33f bugzilla: https://gitee.com/openeuler/kernel/issues/I574AE
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 0f306cca42fe879694fb5e2382748c43dc9e0196 upstream.
For the RODE NT-USB the lowest Playback mixer volume setting mutes the audio output. But it is not reported as such causing e.g. PulseAudio to accidentally mute the device when selecting a low volume.
Fix this by applying the existing quirk for this kind of issue when the device is detected.
