Hi all, With which version of Linux kernel and ALSA is Pioneer DJ DJM-900NXS2 over USB fully supported? I am not sure in which release is: https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/tree/sound/usb/mixer_quirks.c#n2825 and https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/tree/sound/usb/quirks-table.h#n3646 which offer to 10 playback channels and 12 capture channels. I'm using Ubuntu 20.10 which lists it as USB device with playback and capture. Both aplay -l -L and alsamixer reports this. However, I can't seem to use it. A black screen without controls is shown in alsamixer. Sending or receiving audio is not possible when selecting the device in gnome-control. Only the device is listed, not the individual channels. The versions for 20.10 are: Linux 5.8.0-7630-generic alsa-base 1.0.25+dfsg-0ubuntu5 alsa-topology-conf 1.2.3-1 alsa-ucm-conf 1.2.2-1ubuntu5.1 alsa-utils 1.2.3-1ubuntu1 For Ubuntu 21.04, these version are expected: Linux 5.11.0-11.12 / 5.11.0-13.14 alsa-base 1.0.25+dfsg-0ubuntu7 alsa-topology-conf 1.2.4-1 alsa-ucm-conf 1.2.4-2ubuntu1 alsa-utils 1.2.4-1ubuntu2 Will that solve it? thanks, Pander _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
