Let me ask, how are you guys combating the line-in issue. I noticed that if i have XM and HD radio connected, both are very low on volume. If i connect one at a time, they work like they should. I saw this A/V switch that when it senses output from a device it automatically switches to that device. I am hoping that it will keep the quality and not lover it. I am not sure if this will work though because it also has a video port, so Im scared it wont switch with only audio. What can I do to trick it if it turns out I need a video signal for the auto switching?
