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.
