HD Sound Problem - Please Help!!!
Hi folks,
everything was going really well and was loving this combination (Pioneer SC LX85 and CA 751BD) through HDMI for video/sound and analogue for stereo music. Last weekend, I suddenly couldn't get any sound when playing HD soundtracks (Dolby True HD and DTS Master). Have adjusted the CA between bitstream (no sound or DTS) and auto or LPCM (pcm sound). With PCM there is no sound in surround. Rather baffled and not smart enough to work out what I'm doing wrong. Feel it's something really dumb. Video is passing through HDMI but no HD sound. I am finding the pioneer is a complicated piece and I have been button pushing like a fiend so I really think it's me but no idea how to get back to defaults. Any help or advice would be really welcome.
Thanks
Raymond
Have you recently turned on the HDMI control function, I did this recently to test and it removed the setting I had for the Sky optical connection.
Other thought what input are you using for the Bluray and what input for the CD playing.
Have these changed.
Hello Michael Hoy,
thanks for the reply. HDMI control function is switched off on the Pioneer. Have tried it on but no change. Wonder if you could clarify what you mean by input for bluray and input for cd player?
Thanks
Raymond
I use my OPPO 95 in the same way you use the 751.
HDMI for movies and Analogue for CD (Stereo).
The HDMI lead is connected into the BD port at the back and the Analogue cables into the CD input at the back.
Therefore to listen to Analogue stereo I have to choose the CD input.
I do use the HDMI (BD) connection sometimes when streaming music from my server.
Am I right that this is how yours is setup.
Hi,
exactly the same. I have recently added an Audiolab cd player so moved stereo over to that but we have the same set up for video and audio. I just can't work out why it stopped showing HD audio on front of Pioneer. Stereo sounds really fantastic and so did HD but lost for solution. Thanks again for responding,
Cheers

I had a similar thing happen once a few years ago with a Pioneer Ax5i it was to do with "signal select" it's on page 47 of your LX85 Manual. Basically an idiot brother in law had been messing about with the amp when i was out when i went to play something no sound took me ages to suss but it was a couple of button presses of signal select that sorted it
Try it and see if that helps.
Hi v1c
thanks for your input. When I try to signal select on BD it only offers hdmi. It will not switch inputs like other connections that offer hdmi, auto and analogue. Do you know if this is as it should be?
Thanks

Ok try page 58 HDMI Audio
"Specifies the routing of the HDMI audio signal out of this reciever (amp) or through to a TV. When THROUGH is selected , no sound is output from this reciever" (Option AMP THROUGH)
Hi v1c,
I have it set to amp. If I select any other audio on the CA 751BD it plays without a problem. If I want a German or Chinese audio track, I can have that. I just can't have TrueHD or DTS Master in English. Very confused.
Thanks

Ok try the CA make sure you have the secondary dialog set to off someone on another thread said this was the culprit on his oppo.
Hi v1c,
thanks for working through this. Secondary audio is set to off. No change.

I think you need to list your amp settings for BD and AUDIO and your CA settings for AUDIO so we can see what you have set at the moment.
On page 95 of the LX85 manual it says "Note when fixed PCM ON is selected you won't be able to hear any other signal format"?
Running out of options Bell.
Hi v1c,
sorry to be so ignorant but where do I get that information?
Raymond
Something else to check from you CA 751 manual
Page 27 Audio format set up
Note If you use HDMI to connect audio to a HDMI av reciever it is important you choose 720p or higher.....when playing True HD , DTS Master bandwidth available is proportional to bandwith used by video at 480p/576p HDMI only supports 2 channels of audio with high sample rate or 8 channels of audio with standard sample rate if you play high res audio content at 480p/576p you may get reduced audio resolution , incomplete audio or no audio. Choosing 720p or higher allows enough bandwith for high sample rate audio channels.
This is not quoted verbatum so you need to read your maual.
Hi v1c,
sorry to be so ignorant but where do I get that information?

It's in the user manual for the LX85 page 95 so you need to look it up in the manual.
Mauals for the 85 and the CA 751 are both online if you don't have access to them.

Signal select is not a changeable parameter for the BD input, it is changeable on the other HDMI inputs.
