Armbian on cubox doesn't detect external USB DAC any more


wanda

Question

Hi,

 

I run  ARMBIAN 5.25 stable Debian GNU/Linux 8 (jessie) 4.9.12-cubox  
and use an external DAC connected to USB.

Additionally and or comparison purposes I use ARMBIAN 5.25 stable Debian GNU/Linux 8 (jessie) 4.4.51-udoo    .


Since a few days  the kernel on the cubox doesn't seem to recognize the USB-DACs as sound device any more.
So, "aplay -l" doesn't list it:
 

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SPDIF [Integrated SPDIF], device 0: S/PDIF PCM snd-soc-dummy-dai-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0


A test with a udoo-board, shows the expected output:

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: imxvt1613audio [imx-vt1613-audio], device 0: AC97-analog vt1613-hifi-analog-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: imxhdmisoc [imx-hdmi-soc], device 0: i.MX HDMI Audio Tx hdmi-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: Audio [McIntosh Labs USB Audio], device 0: USB Audio [USB Audio]
  Subdevices: 0/1
  Subdevice #0: subdevice #0



On the Cubox I find in "messages" following output with disconnections :

I also checked it with a different DAC to exclude problems with the DAC itself:

Ont the udoo board that looks straight forward without disconnections:

May 27 13:06:06 localhost kernel: usb 1-1.3: new high-speed USB device number 5 using ci_hdrc

Any hint what could be the problem on the cubox ?

 

Thank you !

but the udoo machine loads the driver after turning off/on of the dac:
 

May 28 14:21:12 localhost kernel: usb 1-1.1: new high-speed USB device number 4 using ci_hdrc
May 28 14:21:12 localhost kernel: input: McIntosh Laboratory McIntosh Labs USB Audio as /devices/soc0/soc/2100000.aips-bus/2184200.usb/ci_hdrc.1/usb1/1-1/1-1.1/1-1.1:1.2/0003:2349:03E8.0001/input/input0
May 28 14:21:12 localhost kernel: hid-generic 0003:2349:03E8.0001: input: USB HID v11.01 Device [McIntosh Laboratory McIntosh Labs USB Audio] on usb-ci_hdrc.1-1.1/input2
May 28 14:21:12 localhost kernel: usbcore: registered new interface driver snd-usb-audio

So, this works.

But turning on/off or unplugging/plugging the dac to the cubox doesn't help.

I uploaded images with most recent kernel (4.11.3) - one last check if it's any better. I am not sure we have any power and knowledge to deal with such weirdo / random problem. Perhaps folks at Freescale knows more about?

 

How about old / legacy kernel? Just to see if it's working there ...

I just updated cubox-i and udoo as well to 4.4.71-* .

 

Unfortunately no change armbian on udoo finds the usb-dac, on cubox it doesn't  .

 

Well, last year I already changed the cubox-i device due to a similar "failure".

At that time I didn't run armbian but volumio and first for test purposes I switched to armbian.

The new cubox worked by now and the dealer informed me later that even the complained first device seemed not broken from his point of view and asked me to check my environment.
He tested just the usb-connectivity with a keyboard/mouse.

 

But now I experience in the same way those problems again with the new cubox, i.e only with the cubox .

I also tested with a laptop and debian stretch installed without any problems. So, an environment problem is very unlikely.

 

Is it easy to switch to the legacy kernel or do I have to reinstall completely ?

With latest image - run armbian-config -> Switch / Switch to alternative kernels
