I have a Cambridge Audio Sonata NP30 Internet radio connected by Toslink to the S/PDIF In of a Creative Sound Blaster X-Fi USB DAC. Using Audacity 2.1.3 (installed from Fedora Repository) in Fedora 25 (XFCE) I want to capture music from the NP30, but Audacity doesn’t record it. Tried various settings in Audacity and Pulse Audio Volume Control. Have also tried without .asoundrc and with several .asoundrc configurations.
Currently, I have disabled .asoundrc. AlsaMixer lists the Sound Blaster as a PCM Capture Source [Mic] but has nothing about S/PDIF. FWIW, Audacity does play sound files on the computer through headphones connected to the Sound Blaster.
Any help in solving this would be much appreciated.
