[francesco]

Hi

may i ask a question ?
i did search a lot
well in my desktop i have windows 7 64 , on my laptop i had installed xp sp3 and tried windows 7 32
in the laptop there is a realtek hd

well same laptop , same audio card but under windows 7 i can set 24 playback and to be honest the music play better
under xp i did not find the option to enable the 24 playback


i update the realtek audio drivers for w7 and xp but under w7 i have this screenshot , but under xp same drivers version , i haven't such option




i would like to keep on my laptop xp sp3 , is there a way to have such output?
i use a densen lik amp for my stereo

thanks
cheers

PS i borrow the screenshot because my w7 is not in english

Stop searching, you are confusing two different things.

The setting in Vista/7 just defines the preference for output when mixing, (which is done in legacy mme, directsound, and even wasapi in shared mode).

In your screenshot, a wav file ripped from a CD would play like this
(Player)Wav 44.1Khz 16bits -> (mixer) increase bit to 32bit, resampling to 96Khz, reduce bits to 24bits -> (Driver)reproduce. Generally it would not resample, but that really depends on the manufacturer.

In windows XP, the setup is:
(Player)Wav 44.1Khz 16bits -> (mixer) resample to a samplerate that the driver supports (this meant 48Khz with AC-97 soundcards) -> (Driver) reproduce. Some drivers used internal resampling on the hardware, others used software resampling in the drivers, and others used the resampler of Windows, which could be set to different qualities.
(For a 24bits one, if the driver supports it, the same path applies, so it is automatically 24bits).


In my Windows 7, I have the setting to 44.1Khz, 24bits, since i usually play music sampled at 44Khz, and the players might output at 16bits, 24 or 32bit, so I set to 24bits so that i don't degrade the higher bit-depth ones.
It does not improve at all the 16bit signals (except, maybe if the hardware or drivers do something different depending on the bitdepth).
