Hi!

I'm running a Mytek DSD 192 on a Raspberry 3 with Raspbian stretch. I successfuly compiled the module and installed it on kernel 4.9.59-v7. Device is recognized 👍
But it does not shows up in alsa list..

Any idea how to fix this?

I see lots of mentions about alsa playing but can you record using this with arecord?

Jurgen,

Not sure if the driver is working or not, but to get it to build on 3.20/4.0 ....

Hello,

Trying to figure out an issue with make on Arch. I seem to get this error.

Thank you,

Darin

please help to install this driver of raspberry HIFI.

Hi, just wanted to share my i-know-it-s-dirty-but-so-convenient solution to the known issues 1 and 2 (from the file ISSUES) for anyone googling. The system is Debian Jessie, compilation and installation went great.

• edit new file "/etc/udev/rules.d" (might differ on your system):

SUBSYSTEM=="usb", ATTR{idVendor}=="25ce", PROGRAM="/sbin/rmmod snd-usb-mytek && /sbin/modprobe snd-usb-mytek && /sbin/rmmod snd-usb-mytek && /sbin/modprobe snd-usb-mytek && /sbin/rmmod snd-usb-mytek && /sbin/modprobe snd-usb-mytek"

This udev rule force the module to reload the firmware fully as your suggested workaround but this happens automatically when connecting or powercycling the DAC.

By the way, any chance to see a firewire version of your work someday ? Or should the generic snd_dice module be able to run mytek devices with a patch ?

When making the driver there was an error message:
pcm.c:529:10: error: ‘snd_pcm_lib_mmap_vmalloc’ undeclared here (not in a function); did you mean ‘snd_pcm_lib_mmap_iomem’?
529 | .mmap = snd_pcm_lib_mmap_vmalloc,
| ^~~~~~~~~~~~~~~~~~~~~~~~
| snd_pcm_lib_mmap_iomem
Any ideas?

In debian, alsa cannot find mytek.

Log messages are

I'm using debian with linux kernel 3.10.10 and the mytek firware version is 1.75.

And below message is shown on dmesg.

mytek: Pre-initialised Mytek with missing FPGA firmware, please cycle its power

I turned mytek off and on and then connected USB cable but it didn't help.

Can it be solved?

Thanks.
