Problems with audio on Panasonic TXL37ET5E

Hello,
hope, somebody helps me. Today I installed Serviio on my PC (Windows 7 64-bit). I just added shared folder to serviio and turn on TV. TV founded serviio well but I have a problem with sound.
.avi, .mkv movies work fine, video and audio is nice
.mp4 tv series don't work fine. I have ~1sec. audio delay.

Can anybody help me please? I have that problem only with tv series :/

Tried enable and disable transcoding. Same result..
Do I need config anything in serviio?

When I turn on transcoding, tv series work fine without any delay.
Thank you

what profile do you have selected for this device under the status tab of your console?

Here you are

have you tried any of the other panasonic profiles for this device?

Yes, but result is the same :/

so wait your saying it works fine with transcoding on? if it's working with this method.. then what's the issue?

If I have transcode enabled, tv series (.mp4) work fine and if I have transcode disabled, other movies don't work fine (subtitles don't work)

so subtitles work only with transcode disabled. If I have TV Serie with subs I have two options:
1. watch with audio delay and working subs (transcode disabled)
2. watch without audio delay and without subs (transcode enabled)

can you post the media info for a tv series file that has audio issues?

we should be able to adjust the encoding profile to only transcode mp4's with a specific audio format.
