Ways to use it with USB DAC #2

Closed lorenzoantei closed 1 week ago

lorenzoantei commented 1 week ago

Hi. I tried to use it with a USB DAC. 

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [HifiBerry DAC HiFi pcm5102a-hifi-0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: UA5 [EDIROL UA-5], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I tried to edit ~/.jackdrc as follow:

$ cat .jackdrc 
/usr/local/bin/jackd -R -P 75 -T -d alsa -d hw:1 -r 44100 -p 256 -n 3

If I boot and tried to play something:

$ aplay /usr/share/sounds/alsa/Front_Center.wav
ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
aplay: main:830: audio open error: Device or resource busy

Getting jackd to work can be quite a struggle. Perhaps my SuperCollider on UniHiker gives better insight:

Done! I follow your guide without built SuperCollider and add this to autostart.sh script:

# ...
# export DISPLAY=:0.0

export JACK_NO_AUDIO_RESERVATION=1 # EDIT

# Retrieve .scd patches
# ...

and with this into ~/.jackdrc:

$ cat ~/.jackdrc
/usr/bin/jackd -r -d alsa -d hw:1

Here an output of autostart script:

~ $ ./autostart.sh
