Griga Posted March 2, 2012 Share Posted March 2, 2012 I have no sound in some HD-channels Audio type? AC3? AAC? MPEG Audio? If AC3, install and select (Options -> DirectX) this decoder: http://ac3filter.net/wiki/AC3Filter but if I record the channel and plays it I have sound? In which player? Quote Link to comment
norings Posted March 3, 2012 Author Share Posted March 3, 2012 (edited) Audio type? AC3? AAC? MPEG Audio? In which player? I use DVBViewer to play recorded files. I have also noticed that if I press pause during a live tv broadcast and then press play again so I get a timeshift I have sound. Edited March 3, 2012 by norings Quote Link to comment
Griga Posted March 3, 2012 Share Posted March 3, 2012 Strange. Audio type? See DVBViewer channel editor... Quote Link to comment
norings Posted March 3, 2012 Author Share Posted March 3, 2012 Strange. Audio type? See DVBViewer channel editor... AAC 5.1 or AAC audio stereo the same as on other HD-channels (SVT1 HD, SVT2 HD, TV3 HD) Quote Link to comment
Griga Posted March 3, 2012 Share Posted March 3, 2012 AAC 5.1 or AAC audio stereo From your SystemInfo.txt: -------------------------AAC Audio Decoders: ------------------------- Microsoft DTV-DVD Audio Decoder V6.1.7140.0: 005FFFFF It's the only one. Try to install others and select them on Options -> DirectX: - The libfaad2 wrapper from the DVBViewer members area -> plugins (read the included ReadMe!!!) - The DivX AAC decoder. It is part of the DivX Codec Pack. Take care to untick everything in the installer that you don't want. Quote Link to comment
majstang Posted March 3, 2012 Share Posted March 3, 2012 AAC 5.1 or AAC audio stereo the same as on other HD-channels (SVT1 HD, SVT2 HD, TV3 HD) Are you sure? Im pretty convinced SVT uses Mpeg and AC3 audio for their HD channels. Quote Link to comment
QBox User Posted March 3, 2012 Share Posted March 3, 2012 So it says here: http://svt.se/2.152197/1.2408782/expert AC3 5.1 and MPEG tracks. OP should still be able to select MPEG audio track if AC3 doesn't work. I see from support files that DVD playback has a Hauppauge AC3 decoder - is that setting used for video playback? Choosing the same AC3 codec for Video A or B might work. Current settings are A: Arcsoft and B: Microsoft, which definitely doesn't work. Quote Link to comment
norings Posted March 4, 2012 Author Share Posted March 4, 2012 Are you sure? Im pretty convinced SVT uses Mpeg and AC3 audio for their HD channels. No problems with SVT and tv3, this is what DVBViewer says. The problem is in TV4 and kanal 5,there is only one soundstream, only live tv not from timeshift or played later with DVBViewer Quote Link to comment
Griga Posted March 4, 2012 Share Posted March 4, 2012 According to this site TV4 HD is broadcasting HE-AAC audio via DVB-T2. Noring is using an Anysee DVB-T2 device (see support.zip). IMO it's only a question of installing/using an AAC decoder that can cope with AAC 5.1. See my suggestions above. There have already been reports about the MS decoder not doing it properly (or not at all, can't remember...). Quote Link to comment
norings Posted March 6, 2012 Author Share Posted March 6, 2012 Tested the libfaad2 wrapper and I got sound but not very good sound, sometime its loud and suddenly it cuts and goes low I must try something else. Quote Link to comment
Griga Posted March 6, 2012 Share Posted March 6, 2012 Tested the libfaad2 wrapper and I got sound but not very good sound, sometime its loud and suddenly it cuts and goes low That's a known problem with the underlying libfaad2 decoding library and some transmissions. The DivX AAC decoder doesn't show this issue (reported by British users). Quote Link to comment
