CS8412 question

[MJPAudio]

Hai There,

I have a DAC with a CS8412 and a TDA1543 but i want it to connect it at my DVD player now i have to replace the CS8412 with a CS8414 but is this a dropin replacement?

Thanks maarten

Why do you have to replace the 8412, I have not checked the datasheet recently but I think it can cope with up to 24 bits and 48kHz which is what you'll at best get out of most dvdplayers.

And yes I believe it is pincompatible.

when i connect it with some dvd's i get a lot of digital noise and no sound i think its 96khz? its some dvd's its sounds great!

If you have a DTS movie then a CS8414 won't help either. I would rather get a DVD player like I have, a cyberhome 462. It puts out converts AC3/DTS to PCM/Redbook standard.


Here is a thread over on diyhifi about replacing a CS8412 with CS8414.

i don't want to play dts but when i select my movie's to 2.0digital stereo i get some digital noise but when i play a movie with 2.0pcm there is sound:S and i think that an CS8414 play with 2.0 digital stereo

It is most likely as Bas says, you are getting a DD or DTS stream, dvd's and players that are encoded and send 96kHz as is are very, very..VERY rare.
If you actually get 96kHz PCM I would think the 8412 would mute or just won't be able to capture the clock which may have the same effect...silent.

Most dvd players have meny settings to convert DD and Mpeg to PCM, some also can convert DTS. Those that do then send it as 16/48 PCM which will be fine with your 8412 reciever.
There is also typically features that let you know what kind of audio stream you have.

hmmm but i wont help if i repalce it by a CS8414 i have a vestel 2851 divx

That's what we are trying to tell you....it won't help to change the 8412 for the 8414.

 

[Bas Horneman]

it won't help to change the 8412 for the 8414.

I think so too.. the vestel is a machine that probably has the same stuff inside as mine...ie it can convert almost all formats to PCM...?? I suppose all PCM is 44.1kHz?
Maybe if you know that you know the answer...

 

[MJPAudio]

maybe i am stupid but how can i get it to work when i play SADE lovers live it wont play at 2.0 or 5.1 only the analog output but when i play Simon and garfunkel at 2.0 then it plays on the analog output and digital output.

[Bas Horneman]

Maybe Simon and Garfunkel also has a stereo PCM 16bit/44.1kHz track?

OR

Your Vestel player does not do its job as advertised?

OR

The Vestel player can convert everything to PCM but some at a higher sampling rate...in which case you MIGHT be helped by a 8414. Might because my DAC can accept sampling rates up to 192kHz, and who is to say at what sampling rate the Vestel outputs it PCM. Hopefully someone who really knows his story can help us.

Cheers,
Bas

2.0 can be either pcm, dd or mpeg, 5.1 can be dd, dts or mpeg so what is it you are refering to?

Just get into the menu system of the player, find audio options, digital out and set them all to PCM!? You should be 99% covered by then.

If it still don't work you probably have some sort of copyprotection that stops the spdif feed.

No dvdplayer upconvert digital out, its 48kHz or 44kHz depending on the source. If it was a 96kHz disc almost all players downconvert to 48kHz on the digital output.

 

[Bas Horneman]

If it was a 96kHz disc almost all players downconvert to 48kHz on the digital output.

You could be right. That makes perfect sense to me.

 

[MJPAudio]

hmmm i have set the output to 96khz and it does the same as on 48khz it only plays pcm2.0 records

Just get into the menu system of the player, find audio options, digital out and set them all to PCM!? You should be 99% covered by then.

Again, get in there and make sure you have set DD, Mpeg and (DTS) to PCM and try once more.

Often DVD players are intractable with respect to the audio data. You might try using a PC to play the DVD. Normally a computer program will give you total control over the playback. Especially flexible are mplayer and vlc.
