sound card with mp4museum sync

[peterboogle]

Dear julius,

i use a DAC iQaudio pro (for balanced output). It works well with mp4museum V5.5 and alsa.txt file. But it doesn't work with mp4museum sync version.

however the card is correctly detected :

  pi@mp4museum:~ $ aplay -l
  **** List of PLAYBACK Hardware Devices ****
  card 0: b1 [bcm2835 HDMI 1], device 0: bcm2835 HDMI 1 [bcm2835 HDMI 1]
    Subdevices: 4/4
    Subdevice #0: subdevice #0
    Subdevice #1: subdevice #1
    Subdevice #2: subdevice #2
    Subdevice #3: subdevice #3
  card 1: Headphones [bcm2835 Headphones], device 0: bcm2835 Headphones [bcm2835 Headphones]
    Subdevices: 4/4
    Subdevice #0: subdevice #0
    Subdevice #1: subdevice #1
    Subdevice #2: subdevice #2
    Subdevice #3: subdevice #3
  card 2: IQaudIODAC [IQaudIODAC], device 0: IQaudIO DAC HiFi pcm512x-hifi-0 [IQaudIO DAC HiFi pcm512x-hifi-0]
    Subdevices: 1/1
    Subdevice #0: subdevice #0
  pi@mp4museum:~ $ 

I can also access the iQaudio card settings in alsamixer, but from the menu "sudo raspi-config", I can't select it.

is it possible to change the audio output in mp4museum Sync ?

Thanks so much best, Pierre.

Dear Pierre,

sorry to say that there is, at least to my knowledge, no way to route audio from the sync version other than hdmi or analog out. omxplayer-sync is quite old now and has seen no updates in years, i am still looking for a replacement.

if you need high quality audio, i can only suggest to use hdmi out and get a audio de-embedder. it will take the audio stream from hdmi and usually provides spdif digital and/or stereo analog output.

best, Julius.
