I'm trying to use the Cirrus Logic Audio Card and RPi2 in a Software Defined Radio application. Specifically the Softrock RXTX Ensemble: WB5RVZ - Home Page
I was hoping I could use this card to do both RX and TX, but it's not clear how I can present the various inputs and outputs to the SDR software. I'm working with Quisk right now (apt-get install quisk).
Normally I would present an audio device as hw:0 and hw:1 and so on. This card only has hw:sndrpiwsp and I have to use the various scripts to activate inputs/outputs.
I only need to record and playback from one input and output at a time, but the trick is helping the software to switch between inputs and outputs when I push the transmit button. Right now taking the Record_from_lineIn audio processing that in Quisk and then having the output from Quisk go to the headphone jack works like a champ. I have to manually run the scripts and change to Record_from_DMIC and Playback_to_Lineout.sh which is rather clumsy.
So anyone know if I can use something more specific than a generic hw:sndrpiwsp device?
