Default Mgcamd 1.35 & Mgcamd 1.38c AC3 encrypted audio

Hello, will try to explain detailed.

Mgcamd won't decrypt AC3 audio, Mp2 and aac are working ok.
This particular channel only has 1 single AC3 audio stream, so No sound , only video decrypted.

Box DM800HD with OpenPli 4.0 Mgcamd 1.35/1.38c + single N line (on local PC server just for test).
From Mgcamd log:
got 57 cmd 9F
[mg0] namespace C00000 t-id 1 on-id 1
[mg0] descramble on 1, source 0
[mg0] service 279 index 0 pmt pid 37F (1), pids: video 0x037A, audio 
[mg0] ECM: CaID: 0x0604  -> CaPID: 0x05DB ProvID: 000000
Maybe some problem with pmt parsing, or ES type 129
(to get correct audio pid inside Mgcamd).
Recording TS file gives clear video with encrypted AC3 audio present.

dvbsnoop output:
Stream_type loop:

    Stream_type: 27 (0x1b)  [= AVC video stream as defined in ITU-T Rec. H.264 |

               Audio_type: 1 (0x01)  [= clean effects]
Same setup/Image with oscam + newcamd reader works fine on same AC3 audio channels.

after carefully reading at various forums can't find solution to my problem, just change softcam.
