San Francisco - Smallville No Sound?

Yes. Sound cut out just before Smallville started, returned just after it ended, then cut out again just before Angel started, and returned after Angel ended. Sound was present on 20.2, the SD version of the broadcast.

Same here in Berkeley..


No sound on my new LG LST-3510A HD receiver..


Was worried a bit since I had problems getting sound from the NFL game on FOX this past weekend too

For a while I was thinking it was intentional - the ep was about Clark's hearing going haywire, sort of like the all silent episode of Buffy. Then I realized I could switch to the sound from my cable box. One nice thing about the way the SF WB affiliate broadcasts is that they keep the SD and HD broadcasts in perfect synch, so you can mix and match sound and picture.
