I'm servicing a Canton AS 80 SC powered subwoofer. I replaced the power
output IC and it worked for a few minutes but the next time I powered it on,
the output was next to nothing. I found the datasheet for the TDA7294S here.

I am trying to determine if the muting is activated by a high or a low input
on pin 10. I'm guessing that a high input mutes the audio but I'd like other
opinions.

Thanks for your reply.
