alsa-project/alsa-ucm-conf issue #518 was opened from pv:
Similar issue as #515, and related to #444:
We have a report https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4602#note_2819696 that GoXLR UCM profile with SplitPCM=1 specifies always 23 channels, but the device can't be opened with exactly 23 channels. According to https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4602#note_2819696 the device may have 21, 23, or 25 depending on firmware/etc details.
In Pipewire, I think we add a workaround that just uses the available channel count even if it is different from what UCM profile specifies, but logs warnings if the counts are different so these issues in the profiles can be caught.
