[alsa-devel] MiniDSP USBStreamer / UAC2 / Alsamixer bogus
Hi there,
Today I received a MiniDSP USBStreamer Box. (http://www.minidsp.com/products/usb-audio-interface/usbstreamer-box) It's an USB to ADAT optical interface and claims to be UAC2 compliant. It's based on a XMOS L2 core.
Audio worked out of the box! 8-Channels In & Out :)
But the alsamixer controls seem to be bogus. Here's a screenshot of qasmixer: icem.folkwang-uni.de/~jb/geheim/usbstreamer_qasmixer.png
All controls are named "USBStreamer Clock Selector"... The first control always snaps back to zero. The following 8 Multi-Controls don't have any effect. Only the last two Input/Ouput Master controls work as expected.
The most important problem is that I cannot set the clock source:
amixer -D hw:USBStreamer cset numid=7 1
numid=7,iface=MIXER,name='USBStreamer Clock Selector' ; type=ENUMERATED,access=rw------,values=1,items=2 ; Item #0 'USBStreamer Internal Clock' ; Item #1 'USBStreamer ADAT Clock' : values=0
The value always stays 0 (internal).
On OS X 10.8.5 without installing any driver I see 8 Input/Output Volume Sliders + Master Sliders and a working Clock Selector.
I'm running debian testing with a 3.13-1-amd64 stock kernel.
Any ideas? I've attached lsusb and amixer infos below...
Cheers & Thanks, Jan

Today I received a MiniDSP USBStreamer Box. (http://www.minidsp.com/products/usb-audio-interface/usbstreamer-box) It's an USB to ADAT optical interface and claims to be UAC2 compliant. It's based on a XMOS L2 core.
Audio worked out of the box! 8-Channels In & Out :)
Nice!
But the alsamixer controls seem to be bogus. Here's a screenshot of qasmixer: icem.folkwang-uni.de/~jb/geheim/usbstreamer_qasmixer.png
All controls are named "USBStreamer Clock Selector"...
That's strange indeed.
The first control always snaps back to zero.
This is likely a separate problem.
The following 8 Multi-Controls don't have any effect. Only the last two Input/Ouput Master controls work as expected.
Could you read through Documentation/usb/usbmon.txt and follow the instructions there? Then capture the packets that are transmitted when you try to set the ALSA controls with amixer. I'd like to know whether the right units are addressed at all. Make sure to denote in the trace which amixer control you set, and which traffic resulted from that.
Also, a snapping back control means that the driver got an interrupt from the device. The corresponding packet should also be visible in the dump.
On OS X 10.8.5 without installing any driver I see 8 Input/Output Volume Sliders + Master Sliders and a working Clock Selector.
Ok, so that means it's definitely a bug on our side.
I'm running debian testing with a 3.13-1-amd64 stock kernel.
You can already build a kernel from today's sound master git, as this is the base for new patches:
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/
Any ideas? I've attached lsusb and amixer infos below...
Excellent - thanks a bunch for such detailed information!
I'll hope to find some time soon to comprehend what's going on.
Thanks, Daniel

because it actually is bLength of the next descriptor. So there's definitely a problem in the USB descriptors, I'm just not sure how we should deal with that.
I'm also not entirely sure if that explains your control name trouble. If you're interested in debugging this, have a look at the function sound/usb/mixer.c, function build_audio_procunit(), especially the lower half where we try to determine a nice name for the new control. You could start dumping the variable 'nameid' and see what it contains.
Also, this device reports strings to describe the channel names (iChannelNames), which the driver currently doesn't care about. It might be worth fetching them and see what they contain. On the other hand, ALSA doesn't allow us to provide names for individual sub-controls (for each of the 8 mixer values inside one control).
Are you up for a little trial and error? I doubt that this will fix your clock selector trouble though, but for that, the usbmon traces should give a hint.
Best regards, Daniel
Hi Daniel,
Thanks for the guidance! I don't have the unit at hand right now, but will give it a try next week and see what I can find...
All the best, Jan
