Rasp Pi 2 + M2tech Hiface 1 - Anyone tried?

[pitadavespa]

Hi Luis,

Would mind running the short procedure below and posting the output from commands (5) through (8) ? I was thinking a bit and want to rule out a possible ALSA issue.

(1) power off the Pi
(2) plug in USB DAC
(3) power up Pi
(4) ssh root@moode (pwd = moode)

(5) lsusb
(6) cat /proc/asound/cards
(7) cat /proc/asound/modules
(8) cat /var/log/dmesg

For #8, just post the "usb" lines. They look similar to below. There will be several groups of them.

[ 3.079837] usb 1-1.3: new full-speed USB device number 5 using dwc_otg
[ 3.268783] usb 1-1.3: New USB device found, idVendor=1852, idProduct=7022
[ 3.287974] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0

Hi Luis,

The line "[ 3.253215] usb 1-1.4: config 0 descriptor??" indicates Linux USB subsystem is not able to read the device descriptor in the DAC's firmware.

If you run lsusb -v there should be line similar to below somewhere in the output.

"Couldn't open device, some information will be missing”

Thanks Tim,

I'll do that and let you know.

Does that mean there's nothing I can do to make it work?


Kind regards,
Luis

Hi Luis,

It would appear that there is nothing that can be done.

Well, if that confirms, it seems the right move is to decide if I buy a DAC or "just" a board with a digital out (S/PDIF prefered) and use my external DAC.


Thanks everyone,
Luis

I have been using raspberry pi and 2 and also the cubox-i with my jkdac32 for a while, its hiface 1 based so uses the same driver. Wasn't aware it was entered into the kernel though, that bit of text about mainline wasn't in when I built the RPI2 sd card. I ended up resorting to installing arch linux and setting up MPD myself. The best bet of the prebuilt ones is probably Rune Audio as it uses Arch as its base, so you should be able to get the kernel headers unlike rasbian, only issue I had is a full upgrade is necessary and that managed to break the web interface last time I tried. , and you may have to resize the partition if the image is 2GB (not too hard if you know how).

The driver also doesn't work any more on the current kernels. It used a deprecated function which has now been replaced (snd_card_create needs changing to snd_card_new, with the usb interface struct passed in to the function). I managed to tweak it so it works again after an awful lot of googling to locate the problem.

I will try and help if you really want to get it working, but it can be a pain in the bum.

The dacs that you get for these are super. Ive got both the sabre one and the iq one and they are both great. work easy peasy on moode too.

Hi Chaps,

I've not been on here for a long while. I just setup Volumio with a hiface usb dac and it wasn't trivial and most of the guides were out of date. I've stuck my scripts on github:
