alsa-project/alsa-ucm-conf pull request #836 was opened from willyp713: Add UCM2 support for the Audient iD14 MkI USB audio interface (`2708:0002`). The HiFi use case exposes: - two logical stereo playback pairs (`Output 1/2` and `Output 3/4`) - two mono analogue capture devices (`Mic/Line Input 1` and `Mic/Line Input 2`) The Direct use case preserves the raw 4-output/10-input stream for DAWs. This follows the existing iD14 MkII profile's policy of leaving the state-dependent digital capture channels out of the ordinary desktop profile. The device's FU12 monitor-mix volume behaves asymmetrically below unity. The card-level `FixedBootSequence` initializes all four channels to 0 dB on boot or hotplug, including when Direct is selected (Direct has no verb). The HiFi enable sequence reapplies unity. A `ControlExists` check supports both the historical `Speaker Playback Volume` control and the `Monitor Mix Playback Volume` name from the accepted kernel quirk: https://lore.kernel.org/r/[email protected] Hardware-tested on Bazzite with PipeWire 1.6.8 and kernel `7.2.0-ogc4.1.fc44.x86_64`, including both playback pairs, mono inputs, Direct access, channel isolation, software volume, and a physical USB reconnect. The current upstream validator also passes against: - alsa-ucm-conf `00175aa645c482111d096c3d8230f182a875d286` - alsa-tests `53d34b6` The required `alsa-info.sh` output will be attached to this PR.
