I have installed Volumio on a raspberry and connected it to my DAC (atoll 100) with an USB cable. After few hours, the music stops. Inside the mpd logs, there are these lines:
Aug 16 10:39 : alsa_output: Failed to open "Output" [alsa]: Error opening ALSA device "default" (snd_pcm_hw_params): Input/output error
Aug 16 10:39 : output: Failed to open audio output
I googled it but I did not find any solution to my problem. I tried this solution. It did not worked.
When I tried the aplay -l:
sudo aplay -l **** List of PLAYBACK Hardware Devices **** card 0: DAC [USB Audio DAC], device 0: USB Audio [USB Audio] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA] Subdevices: 8/8 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7
lsusb also shows my DAC.
cat /proc/asound/cards gives me:
0 [DAC ]: USB-Audio - USB Audio DAC Burr-Brown from TI USB Audio DAC at usb-bcm2708_usb-1.3, full speed 1 [ALSA ]: BRCM bcm2835 ALSbcm2835 ALSA - bcm2835 ALSA bcm2835 ALSA
If I reboot my Pi, music plays again. Does anyone have an idea how to resolve this issue?
