I have already replied that the black list does not work since arecord
can still open iec958
and David expect the patch will make pulseaudio cannot open ice958


arecord -L

iec958:CARD=U0x46d0x992,DEV=0
    USB Device 0x46d:0x992, USB Audio
    IEC958 (S/PDIF) Digital Audio Output



$ arecord -D iec958:2 -f dat /dev/null
Recording WAVE '/dev/null' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
arecord: set_params:1101: Channels count non available

$ arecord -D iec958:CARD=U0x46d0x992 -f dat /dev/null
Recording WAVE '/dev/null' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
arecord: set_params:1101: Channels count non available
