Maybe your device is only siplex instead of duplex?

More likely however, this is simply caused by using the "hw:0,0"
device string, which is really bad style anyway. Use "front:0"
instead. Or even better (on any recent PA version) "device_id=0"
instead of "device=..."

Also, on more recent PA versions it is recommended to use
"module-alsa-card" instead of "module-alsa-sink" and
"module-alsa-source". This will automatically detect all possible
combinations of input and output.
