I’m developing an audio-based application that processes the signal received by the Beagleboard. Since the audio analog connector (AUDIO IN on the card) suffers from heavy noise and other disturbances on my card, I want to use numeric audio.
I’ve been trying for some time to get an external USB sound card to work with Angstrom but I didn’t succeed (the S/PDIF optical input is not recognized by ALSA).
What I’ll be asking here are : what other options to I have ?
Can I use the HDMI port to acquire audio through ALSA ?
Is there any cheap USB soundcard that natively works with Angstrom ?
Can I get audio using another method ? I’m thinking about network streaming, this kind of things.
If you have another suggestion for another numeric connexion, I’m willing to hear your thoughts.
Of course, my favorite option would be to get my current USB soundcard to work ; also, I would really prefer using a soundcard so that I can use optical link over anything else.
Thanks in advance for any help !
