Hello,
I bought DVBSky T9580 and I have a problem to tune stations with AAC audio.
These channels do not work:
Channel name: TV2 or RTL Klub (Terrestrial Hungarian)
Video: H.264
Audio AAC
Provider: MTM-SBS Zrt
Tested AAC Codecs: AC3Filter, LAV Filters, FFDShow, Microsoft no one work with DVB Dream and AAC channels (other formats MPEG-1 or AC3 work fine with H.264).
LAV Filters and Microsoft work fine with AAC audio with DVBSky Player bundled with T9580 (software use DVBViewer technology).
Status Input LAV Audio Decoder from DVB Dream:
Codec: aac
Channel: 51/0x0
Sample Rate: 48000
Format: 16bit Integer
Status Input LAV Audio Decoder from working DVB Sky Player:
Codec: aac_latm
Channel: 2/0x3
Sample Rate: 48000
Format: 32bit Float
Status is from same channel (TV2).
Recording AAC channels work fine, please help.
PS: Please add to DVB Dream support multiple tuners or more tuners in one windows.

Can you capture and send me some sample stream for me to work on ?
How to capture a sample stream
1) Depending on the device you got there, you might first need to enable "Full TS" mode in device options & restart DD
2) start "TSWriter" (or "Stream Recorder") module on the problematic transponder, record about 100 mb
3) upload file to somewhere (Pcloud, Rapidshare). and send links to me

I see you have make some fixes for AAC in DVB Dream v2.7, but I can not test it, because my DVBT2 tuner not work with new version (impossible select or scan channels).
See attached files, one scan with working v2.6a and one scan with new v2.7 (Sat tuner working in both versions):

- Scan_DDv2.6a.jpg (56.59KiB)Viewed 15596 times

- Scan_DDv2.7.jpg (56.57KiB)Viewed 15596 times
I think new version need more developments.
PS:
2015.05.07 have send your with Private messages link to sample stream, hope your get it.

Yea, I got your sample stream and worked on that to fix the problem.
There might be a new bug related to DVB-T.
Can you test by taking the bda.dev from v2.6a and coying it into v2.7 ? To see if my latest changes caused problem with DVB-T2 .
I also attach bda.dev from v2.6a here. You can just copy it into DVBDream\devices folder

Thanks for quick answer, I tested old bda.dev in v2.7, it works (same as in v.2.6a) bug posted on first post still present but I can select and scan channels, only difference i see sound is detected as AAC-ADTS on DVB Dreams main windows.
Edit:
Played little with old bda.dev on 2.7 and its work now, its needed rescan channels (change detected AAC-ADTS to AAC-LATM) after it all channels work fine with Microsoft and LAV Audio Decoder.
Also i think problem with v2.7 is in new bda.dev.

@ru1er, LAV filter v0.65.0.0 should work with AAC without any problem. If you cant get it to work , then can you send me sample stream? please
How to capture a sample stream
1) Depending on the device you got there, you might first need to enable "Full TS" mode in device options & restart DD
2) start "TSWriter2" (or "Stream Recorder") module (under DD main menu->Modules) on the problematic transponder, record about 100 mb
3) upload file to somewhere (Pcloud, Rapidshare, dropbox, google drive etc). and send links to me
