Why will all other TV video and audio channels come in on my indoor antenna except the audio for KOIN Channel 6 in Portland Or?

If you're receiving video from KOIN Channel 6 but not the audio, it could be due to a few reasons. The issue might stem from a weak signal or interference affecting the audio frequency specifically. Additionally, your antenna may not be properly tuned to pick up the audio stream, or there could be a problem with your TV's settings. Checking connections, rescan your channels, or using a different antenna could help resolve the issue.
