P52 audio format issue

Hello,

 

I'm not able to change the output audio format. Only 48k/ 16 or 24 bit is available.

I want to listen to CD music with native 44.1k/16bit. Or use 96k or 192k for HIgh-Res audio. 

Does anyone have the same problem?

Same here on my P72. I guess that's all we get with this Realtek sound card.

Kind regards,

Not really. I have software for testing sound cards. It shows all modes supported by a sound card. 

 

The hardware is actually pretty good. It supports frequencies from 44.1 kHz up to 384 kHz (no visible on the picture) and all possible bit numbers.

But due to some reason, all these modes are not available in Windows 10 settings.

Attached there is a screenshot of another test. It shows real support. Audio data are sent to output and recorded from input simultaneously.

As you can see all modes up to 192kHz are supported in full duplex.

Frequencies higher than 192 were not tested.

Re: P52 audio format issue

I wonder if it is possible to change the driver mode such as WASAPI or at least WDM/KS.  If we could get WDM we should be able to get other sample/bit rates.  This is kinda strange.  I never relied on an internal sound card for audio.  It just so happens I use a high-end card for audio production.

 

Maybe a little research is needed.

 

Kind regards,

Re: P52 audio format issue

Thanks for the hint!

I'll try to do some research.

 

Actually, I also use an external audio interface. But it's pretty bulky to take it with me every time. So I'd like to have a maximum from the internal sound card.

Hey, Ari, I hear you.

I tried to figure out what part/model number for my realtek card, but to no avail.

Do you have any idea?

No, I've no clue.

But I was thinking to find the model of the chip.

I've tried to install drivers from Realtek's site https://www.realtek.com/en/component/zoo/category/pc-audio-codecs-high-definition-audio-codecs-softw...

 

What I got is not working headphones output + strange sound, sort of MONO. 

Then I returned to the original from Lenovo and everything started working again.

But with the driver from Realtek, I was able to select frequencies other than 48. But 44.1 was still unavailable.

 

Obviously, Lenovo did something with the original drives provided by Realtek.

That certainly seems to be the case.  Hopefully someone may have an answer, if it is possible.  Realtek software sure itsn't helping.
