[PATCH] quirk for Pioneer DJ DJM-250MK2 usb sound card
Hello,
I have created a quirk that adds support for the Pioneer DJ DJM-250MK2 mixer (acts like a USB sound card, but Vendor Specific Class).
Output (from computer to card) is working: 8 channels, 48 000 Hz, S24_3LE.
Input is not working. I tried, but I was unable to make it working even under an officially supported OS with Pioneer drivers - Audacity or Mixxx see the channels, but there is no signal. It probably works only with Pioneer proprietary application. But I hope that even mere output support will be useful for someone. (it is usable for playback, just not for DVS)

Takashi, could you put this patch to sound-next ? A partial support is better than no support.

František, could you resend the patch in a proper format? The original post couldn't be applied via git-am, as it was malformed.
Also, please try to adjust the subject line and the changelog text to be suitable for merging to the tree.
thanks,
Takashi

Pioneer DJ DJM-250MK2 is a mixer that acts like a USB sound card. The MIDI controller part is standard but the PCM part is "vendor specific". Output is enabled by this quirk: 8 channels, 48 000 Hz, S24_3LE. Input is not working.

Hi František,
a few months ago, I was working on patches to support the DJM-900MK2 mixer. I guess they are using a similar format on this mixer, at least your quirk is similar to mine. I did not submit these patches yet because I could not figure out a proper way to support both input and output. I'm not an expert on usb audio, but I'll share my thoughts. At least on the 900MK2, both playback and recording use the same interface:
I: If#= 0 Alt= 1 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=snd-usb-audio E: Ad=01(O) Atr=05(Isoc) MxPS=1024 Ivl=125us E: Ad=82(I) Atr=05(Isoc) MxPS=1024 Ivl=125us
Thus, I introduced a quirk with .ifnum=0 for both capture and playback. The problem is that the device accepts sample rate change commands for the capture endpoint 0x82 only. Both endpoints are then configured to that sample rate. Contrary to that, snd-usb-audio expects that playback and recording is on two independent interface that both accept sample rate changes and can operate on different sample rates.
My first approach was introducing a quirk in sound/usb/clock.c, set_sample_rate_v1(). The quirk rejected changes to the sample rate of one interface when the other was already in use by returning EBUSY. This did work only if the capture endpoint was started before playback, which was not predictable when using pulseaudio. Can anyone help on that? Is there a supported device which I can look at that only allows the same sample rate on both endpoints?
Cheers
Fabian

It probably works only with Pioneer proprietary application. But I hope that even mere output support will be useful for someone. (it is usable for playback, just not for DVS)
