At the risk of sounding foolish, I realised that whenever I select PCM 5.1 Audio, the AVR always registers as 2.0 input. Why is this so?

It depend on the source, and also optical cable only support 2.0 PCM

Source is PCM5.1. Cable is HDMI. HDMI should be capable, right?

What player and what amp are you using ?

does your receiver supports HDMI multichannel LPCM?

Panasonic BD60 and Denon 1909.

You set your BD60 to PCM for both True-HD and DTS-MA? What about your settings in Denon? Auto mode?

I have no problems decoding Dolby/DTS, HD Audio or otherwise to multichannels, only hit the brickwall with PCM codes.

AVR - Auto, I think. Have been fiddling with the AVR settings, couldnt get it to work.

Hmm.. I will double check the player's settings again.

I think its the configurations/settings, just dun know which ones

Don't own the Denon, but normally if you set the AVR to Auto and your BD60 to Bitstream or PCM you will still get full multichannel sound.

If you are getting stereo sound, maybe you are playing around with a mode that is only meant for stereo.

Yeah, I think thats the current setting, thats why I puzzled, AVR input indicates stereo ...

Mebbe I need to play around with the settings once more.

Thanks anyway, Ngto

BTW, Denon 1909 does support multichannel PCM, right?

If you have set everything up correctly, the Denon display will light up as "MULTICH IN", indicating that you are receiving multichannel PCM. If you hit "Status" on the Denon, the display should say something like "PCM 48kHz 3/2/.1" indicating that you are receiving 5.1 channel PCM (3 fronts / 2 surrounds / .1 LFE track).

Since it has the HD decoders built in it should also be able to do Multichannel LPCM.

Ngto, HD decoders and LCPM at AVR is different thing...

Everyone knows it's different thing, BUT "Since it has HD decoders built in it should also be able to do Multichannel LPCM"

Hope you see the diff between "should be able to" and "must be able to"

As far as I know, mostly AVR will able to accept Multi-PCM regardless of HD Decoder.

So What does HD decoders relates to PCM??

Do you know that what a HD decoder does is decode bitstreamed HD audio into LPCM? Whether it's the Player that does the decoding or the AVR that does the decoding in the end it all decodes into LPCM.

If an AVR is advanced enough to have HD decoders built in, it is reasonable to also expect it to have the ability to accept LPCM as well , no?

This is in reply to Lone*Wolf who was wondering whether his Denon 1909 could accept LPCM.

Seems you are trying to make an issue out of nothing

As u say, the TS just ask y PCM become 2.0

Just give a simple answer enough la bro...

Y bring in HD decoders pulak???

Because he buy HD Decoder AVR surely try to bring in HD Audio as well lah. No harm to try solve is problem thoroughly.

Unlike you only want to critise and comment just to prove a point but before this never try to help him with his problem

vince kena hamtam pulak

Lau eh, u also come join the fun??

Yesterday kena not enough is it? ha ha

Haha no lah he hantam me. In the end we all friends here no ?

This is call "Intellectual Interaction"

BTW, just look up the Denon 1909 user manual, confirm can accept Multi-CH PCM.
So the problem should be the AVR setting or BDP setting

Yes , see how his feedback. Anyway still not totally clear what his settings are that result in 2.0 stereo.

Thanks for the tip, yonggoh, this will help with the troubleshooting

Ngto & Vince - Thanks for the feedback, confirm the AVR can multichannel PCM, now will go try fiddle the settings .... again! ...

Just an update confirm AVR reading is PCM 2/0/0. Meaning its not the AVR, its the Player.

Anyone knows BD60 can do Multichannel PCM? If yes, whats the setting? My current's all 'Bitstream', secondary audio 'Off'.

i believe there is an option on the BD60 to Downmix to stereo. Try turning that off and see if that works

i got the bd60 and it plays Linear PCM fine (from my black hawk down, justin timberlake BDs)
lemme check my settings for you now...


here u go sir

can see from 3rd pic the little words "PCM" light up in my Marantz Sr6003

Bro, do u have this problem, when u turn off your tv the 1909 avr sound totally shut down, but when u put your tv on standby the avr sound is still there.

If you bitstream from your BD60 to your 1909, then it's the 1909 doing the decoding. How come it's stereo . What disc are you playing , btw?

Are your speaker setup in the AVR all correct? Or could you have set up your AVR to play through zone B or something? (Don't have Denon, so just wildly guessing ). Better wait for Denon users.

I turn all to bitsream and make sure to turn the BD Video secondary audio to off. As indicated, if you turn this on, some BD disc will give :

1. DTS Master audio to DTS only
2. Dolby True HD become Dolby 5.1

I guess maybe just maybe..

3. Uncompress PCM 5.1 to Stereo PCM niah....

Someone IM me last time, why he still see DTS even though he selected DTS Master audio? Now I know the answer de.

But Lone*wolf already said he set his BD60 to Bitstream and Secondary Audio to 'Off'.

this could be the answer.....

yup, its 'off' but sadly, still doesnt work.

Added on December 2, 2009, 11:09 pmThanks for your visual guides, just what I needed for the BD60 settings confirmation! Unfortunately, though my setting's the same as yours, but I am not getting the results as in yr 6003

hmm.. if my BD60's settings are correct (ala yours), then the issue's with the AVR then?

I guess I really need someone with a similiar BD60 and 1909 combo and replicate their settings

Added on December 2, 2009, 11:17 pmer, no... as in no, i havent tried that before

Added on December 2, 2009, 11:24 pmSpeaker setup should be correct, I am getting all 5.1 channels through other audio codes, except PCM. Yeah, guess have to see what other fellow 1909 users say ..

This post has been edited by Lone*Wolf: Dec 2 2009, 11:24 PM

1909 factory reset

Lone*Wolf, just curious, are you selecting PCM from the Audio options on the disc itself?

Huh? You mean reset back to factory defaults?

---

Added on December 3, 2009, 2:52 pmYup, PCM5.1. It would be the biggest 'DUH' if not!

This post has been edited by Lone*Wolf: Dec 3 2009, 02:52 PM

yea man.... record down your speaker calibration levels before the reset...
dun be scared just do it

ok, just hesitating, thinking that the installer sweated for a while before finishing configuring the AVR. Its a Denon after all ..

Still hoping for other 1909 users that can share their settings/shed some light here

I remember reading about Denon 1909 audio setting. There is a function call Auto Surround mode. That feature has memory that will store the last setting u have for the type of input audio type. Check that if it can be reset or sumthing.

Or it could be a bug. check ur firmware..

The Auto Surround mode is 'Off'.

AVR also got firmware updates?

read this....

I tested my Pan BDP60 and Yamaha AVR 465.

The movie the rock is PCM 5.1. Yamaha AVR shows PCM 5.1 also. See pics attached.
