- M-Audio Audiophile USB connected via S/PDIF (audio out) with my
- Self made 2.6.30 kernel
- Pulseaudio 0.9.15-2
No digital sound with the standard pulseaudio configuration (USB device
detected by HAL)
If I start pulseaudio with the standard configuration, I can use the
onboard soundcard of my notebook without problems. If I connect the USB
sound device, the new device is detected and pavucontrol shows me the new
device together with configuration options. But whatever configuration
option I choose there is no digital signal to my receiver (I can’t test
with analog sound in the moment). In this case I’m using no options to
the snd-usb-audio kernel module.
According to linux/Documentation/sound/alsa/Audiophile-Usb.txt I tried it
with the module options „device_setup=0x01 nrpacks=1”. Now pavucontrol
shows *two* Audiophile USB devices, but none give a digital signal.
To make it work I have to edit default.pa and insert the following lines:
load-module module-alsa-sink device=hw:0,0 sink_name=output_intern
# audiophile usb
load-module module-alsa-sink device=hw:1,1 sink_name=output_digital
Now I get sound via the digital output, but I have other problems:
- pulseaudio won’t start without the connected Audiophile USB device.
- pulseaudio stops working and crashes after a time if the USB device is
So what can I do to configure pulseaudio in a way, that it can play
digital output via the USB device but is able to survice the
Thanks for your help!
Shade and sweet water!
