mpc-hc and dual avis

[jordisound]

I use MPC-HC to play avis (xvid video, audio mp3/AC3). Before today everithing went fine but now I've a strange problem.
Opening dual avi, MPC just play one track audio (track number 2) and i cannot change the audio in the menu. Doesn't works in dual mp3, dual AC3,...
I've downloaded the latest version but didn't fix the problem.

Do you have MPC-HC's internal audio switcher activated? What happens if you toggle it in the options?

np: Hildegard Knef - Ich Liebe Euch (DJ Koze Remix) (DJ Koze - Reincarnations)

well, the problems started when i was trying to syncronize a video and an audio. I activated audio internal switcher to put the delay. Later, loaded video and audio separately, and the audio doesn't work. After this, I deactivated the switcher and the problem started. Later, activating or deactivating the audio switcher the problems continue.
I think the problem was the delay, +37000ms. MPC didn't played the audio with this delay.
Now, I've activated the switcher, put delay on 0ms. And I've loaded a video, it works. Then, I've deactivated the internal switcher and works!!!
I don't know why.
