Oscam-emu now supports powervu without streamrelay (on dreambox only...)

Finally with the release of oscam emu 11213 the bug with only 1st audio option decoded is solved. Now all audio options are working even on dm800se/se v2. Thanks to all who made this fix!

Not really.
I see the same behavior,only first audio is decoded.
You might have tested on a channel that has second audio not encrypted,that's the only case I see it works.

I have tested on all channels with ac3 sound and that with previous oscam emu versions are not decoded. With 11213 all are working, so no, in my case it's not like your case. Box: Dm800se V2 with OpenAtv 5.2

In a DM 800HD SE-oscam the emu works perfectly PowerVu but with a DM800 PVR, using the same file no. The confgurations of oscam are different for the DM?

Ok,I tested on DM800,so it should be like you say,something different with the box for audio

I tried this file but nothing worked (that is, no Powervu channels opened at all). I renamed the previous bin file to oscam.old and copied the new one (link above) to usr\bin and renamed to oscam which was the name my file had and set mode to 755. My previous Oscam worked with the limitation of 1 audio track. I have DM 800 HD Se and OpenPli 4. Can someone please tell me where I did wrong as I am not a DM guru. If copying is not the method, how do I install this file?

Do not copy. Delete completely the previous oscam bin file(but first do a backup of that file) and after that copy the 11213 emu file in usr/bin.

You can rename the old Oscam file you need to ftp in binary the new Oscam file and set it 755

Seems to decode all ac3 soundtracks on d*sc0v3ry 1w using DM800 HD, it worked on A*N not sure if ac3 works on s*s 4.9e though :(

Powervu second/third audio sometimes use different decryption key than first audio to decrypt,sometimes the same.
It makes testing a bit difficult.
CSA doesn't have this problem since it uses the same key for video and all audio (but it can be setup to use different key,just not used that way).
This is what makes it easy for emus to decrypt all CSA encrypted audio,and a hell of a problem for powervu/DES audio.

You are mixing up Conditional Access Systems (CAs) and encryption modes. CAs are for example powervu, crytoworks, nagravision, etc. Each uses a different method to decrypt the Code Words (CWs) used to decrypt the video/audio tracks. Most systems use CSA (Common Scrambling Algorithm) to decrypt the streams once the keys (CWs) are decrypted. Powervu uses mostly DES (Data Encryption Standard) but also some channels use CSA.
