Don't Panic! NXE Update Incoming Tomorrow

Hmmm... ok, I think I was suffering from that problem without even knowing it.  I run my blu-ray, 360, and cable box via HDMI, through and switched by my surround sound system.  I found that most times (not 100%, but enough to change the way I do things), the sound system would only detect stereo sound coming from the 360.  I found that if I set the sound system to cable first, then switched to the 360 after letting it boot up for 10 seconds or so... it played everything in 5.1 without further problems.  Failing that, a hard or soft reset was enough to get things cracking in glorious 5.1 surround sound.  I just assumed it was some bizarre quirk of the 360, or even possibly my tv or sound system, or some combination of all those.

However, with the prompting of this thread, I tried booting up the 360 without setting the receiver to cable first... and it worked fine, 5.1 sound from the get-go.  Problem solved, it would seem.
