[PATCH 0/4]: ALSA: usb-audio: Add Pioneer DJM-850 support
Hello,
This patches serie adds support for the Pioneer DJM-850 mixer. The mixer has a 24bits (little endian) sound card, which features 4 stereo channels for capture and 4 stereo channels for playback. The mixer also has controls to specify the capture source for each channels, and also a control to set the sample rate (44.1kHz, 48kHz, 96kHz).
Thank you :)

This specific fix should be applied separately for 5.12. Could you split this one and submit as an individual fix?
I'm currently thinking of merging the rest for 5.13, as 5.12 merge window was already closed.
thanks,
Takashi

Hello,
I updated the patches to consider the request to split patch #3 (c.f. https://mailman.alsa-project.org/pipermail/alsa-devel/2021-March/181275.html ).
The patch #3 now only contains changes related to DJM-850 support as the fix it was previously containing was applied in linux 5.12 (c.f. https://mailman.alsa-project.org/pipermail/alsa-devel/2021-March/181279.html ).
The patches should be ready to merge into linux 5.13 .
Thank you :)

Unlike the other DJM, the value to set the "CD/LINE" and "LINE" capture control options are inverted. This fix makes sure that the displayed info label while using `alsamixer` matches the input switches label on the DJM-850 mixer.

Hello,
I updated the patches to consider the request to split patch #3 (c.f. https://mailman.alsa-project.org/pipermail/alsa-devel/2021-March/181275.html ).
The patch #3 now only contains changes related to DJM-850 support as the fix it was previously containing was applied in linux 5.12 (c.f. https://mailman.alsa-project.org/pipermail/alsa-devel/2021-March/181279.html ).
The patches should be ready to merge into linux 5.13 .
Thank you :)
Patches list :
[PATCH v2 1/4] ALSA: usb-audio: Add Pioneer DJM-850 to quirks-table [PATCH v2 2/4] ASLA: usb-audio: Declare Pioneer DJM-850 mixer [PATCH v2 3/4] ALSA: usb-audio: Configure Pioneer DJM-850 samplerate [PATCH v2 4/4] ASLA: usb-audio: fix Pioneer DJM-850 control label
Applied all four patches now (with correction of subject prefix :)
thanks,
Takashi
Unlike the other DJM, the value to set the "CD/LINE" and "LINE" capture control options are inverted. This fix makes sure that the displayed info label while using `alsamixer` matches the input switches label on the DJM-850 mixer.
