Re: Can you do me a favour and try driver V1.61 on XP?

Well, I **finally** got around to trying these experiments.
I downloaded and installed the Realtek Driver Release 1.61
and installed it on the machine with the Asus P5W DH Deluxe
motherboard.

The information display panel (brought up by clicking the 'i' button)
in the Asus Sound Manager application) now reads:

Audio Driver Version: 5.10.0.5377
DirectX Version: DirectX 9.0c
Audio Controller; HD Audio
Audio Codec: ALC882

Also in the Asus Sound Manager, on the S/PDIF Settings
screen, the Output Sampling Rate section still only shows
48 kHz as an option.

Now, as far as bit-depth is concerned, I performed the following
test (aided by the fact that this machine, in addition to the
on-board Realtek, **also** has two PCI sound cards: a
Creative X-Fi **and** and an E-MU 1212M):

======================

Part 1. X-Fi output to E-MU 1212M input:

I set up Winamp 5.33 Lite with the following options:
General Preferences/Playback: Allow 24 bit and Use Dither both checked.
Plug-ins/Output: HQSoftProc Software Resampling v4.6 Pro (out_HQSP_Resampling.dll)
The latter configured to use:
Output BitResolution: 32
Enable resampling checked
Kernel precision: 150
Target resampling samplerate: 48000
Winamp output plugin used: DirectSound output v2.46 (out_ds.dll)
The **latter** configured to use: SB X-Fi Audio (9880)
Hardware acceleration and volume control disabled.

I connected the S/PDIF optical out of the X-Fi to the
optical input of the E-MU 1212M. E-MU PatchMix was set
to use S/PDIF on the optical input, and to use a 48 kHz
internal sampling rate. The PCI Card S/PDIF L/R input strip
was given a Send to ASIO IN 1/2 - HOST.

Started playback of a playlist of 16-bit/44.1 kHz WAV files
in Winamp ("Agnetha & Frida - The Voice of ABBA", FWIW ;-> )

Fired up WaveLab 5 with Options/Preferences/Audio Card set
to Playback/Record: E-DSP ASIO (9C00). Turned on Live Input
and the bit-depth meter in WaveLab, and saw 24 bits active.

Result: 24 bits active

======================

Part 2. Realtek output to E-MU 1212M input

I used the same configuration as above (including the
48 kHz software resampling in Winamp), **except** that:
A) The Winamp DirectSound output device was set to Realtek HD Audio output
B) The optical cable was reconnected from the optical out of the Realtek
to the optical input of the E-MU 1212M.

Again, I fired up WaveLab 5 (using E-DSP ASIO) and turned on
Live Input and the bit-depth meter.

Result: 16 bits active

======================

Bummer all around! Oh, well.
