I want to use my Pi as an AirPlay receiver for my home hifi (as well as being an OwnCloud server!). I have installed AirPi on it, and I now want to route audio via a USB soundcard as I cannot use HDMI on my hifi and the analogue output just doesn't sound all that great.
Reading around, I saw that the Fiio E10 USB D/A converter I have seemed to work fine with ALSA ( example here: http://benjamin-steininger.de/2012/04/3 ... ude-e6510/), and when I plug it in and run alsamixer, I can press F6 and see the device there. However if I switch to it, I don't get any sound coming through (and I'm testing it using a local WAV file and using aplay to play it).
Also, if I type "aplay -l" then I get this:
Code: Select all
**** List of PLAYBACK Hardware Devices **** card 0: 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 card 1: Audio [DigiHug USB Audio], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Audio [DigiHug USB Audio], device 1: USB Audio [USB Audio #1] Subdevices: 1/1 Subdevice #0: subdevice #0
I have a few queries here and I'd love it if someone could help me out, because I've been searching for hours now and I'm still flummoxed!
Really my queries are as follows:
1) How can I force audio to route via USB? I know you can use "amixer cset numid=3 x" to set it to either auto, HDMI or the analogue output... but I don't know how that applies to USB. Or am I missing the point completely here?
2) Am I right that if I can see my device in alsamixer then it is configured and working fine? Or am I over-simplifying things?
Basically I just can't figure out a definitive way to manage and configure audio. I've a feeling this Fiio E10 would work, though FWIW I do also have a Soundblaster X-Fi Go which I could use too if need be....
Help! Any advice (or a link to a definitive guide on the matter!) would be much appreciated...
