| Subject: ALSA: usb-audio: Add mute TLV for playback volumes on RODE NT-USB |
| |
| From: Lars-Peter Clausen <lars@metafoo.de> |
| |
| 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. |
