Perhaps I should have known something was wrong earlier on in the evening.
Friday night, I'm watching the Rays game with Texas. I'm also on the computer which sits to the right of my TV in the bedroom, which prevents me from noticing the ore-game show has no sound. I don't have the TV on mute, so there should be sound.
I do some chores and get back to the game at about 7:30. Now there's audio, but it's in Spanish. Again, I'm not generally concerned about it, so I fiddle around on the computer some more. I know the Spanish announcers will go into some high pitched exclamations if something good happens, plus it could be some sort of technical issue on the broadcasters end.
Midway through the game, it's still in Spanish. Now I'm thinking its something wrong on my end. I pour through the various audio settings, and restore settings to their defaults. BOOM! There's the voice of Dewayne Staats calling balls and strikes.
Somehow, my TV had found and switched over to the SAP audio channel. Don't know how it happened, but it did. Weird.
