Barbara...
Sorry for the delay in responding...
I had checked prior the "Audio" settings and there is currently no other choice but "Modem #0 Line Playback". It's as if the board is not recognizing the sound chip.
This machine is a Sony Vaio PCV-RX540
Not sure if the make and model helps........
Also, I'm still a little confused as to how my drive volumes got switched.
Me thinks Sonys recovery discs need a wee bit o'tweeking
