Looking at the schematic on p.19 the only thing that seems to be common to both the A and B decks as far as no audio from the cassette tapes is concerned would be if there was a problem with the Record switch on the B deck.
Audio from both tapes is sent to the pre amp IC 301, as is also the audio from the radio. The audio output circuit from the pre amp is common to both tape and radio and since the radio audio is OK, obviously something is telling the pre amp not to switch through the tape audio.

I'm thinking that you would still hear audio from the radio if the Record button was operated because this would allow you to record tapes from the radio but if the record button was "operated" (even though it appears not to be) this in effect would stop you hearing audio when playing a tape as you can't listen to a tape and record at the same time, unless I suppose you tape from A to B.

The Record button is switch S903 seen on p.4 (Sony part #1-771-059-11). Perhaps it is not functioning correctly.
