Question
wanda
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

Any hint what could be the problem on the cubox ?
Thank you !
