I upgraded from 1.2.3 using the individual deploy packages.
When I first started MP and LiveTV, the sound was muted and I had to press the Mute button on my remote to unmute it.
This morning, after resuming from standby I had an error that Windows Explorer had crashed and MP was also locked up so I killed it with my wireless mouse. After restarting MP, LiveTV was again muted and this time I couldn't unmute it with the remote. I closed MP and saw that the Volume Mixer systray icon showed it was muted, so I unmuted that and restarted MP and it was OK after that and I can toggle mute with my remote in MP now.
I'll see what happens after the next resume from standby, but it looks like there's an issue with mute, which I never had previously (I recall reading about some people having trouble with this, although that might have been with digital receivers, whereas I just use the analog output).
