Trying to figure this out: So because some headunits don't have the capability to accept the current 96kHz mode instead of the past 44.1, 48, or 88.2 kHz, this has now become a DP811 software issue instead of a lack of features for some specific hardware? Heck I would think this would be a great research question when shopping for an A/V headunit. Well above is it THX or how many watts do I get. Granted this is a chip producer, but they should be able to provide info on a "set-top" solution for users that do not wish to upgrade to a more A/V friendly or feature-rich headunit. Here is a cut & paste from the VR-3080 users guide stating that is DOES NOT accept the 88.3 kHz or 96kHZ sample rate. Found at
LIVE MANUALS
Digital Audio Section
Sampling Frequency - 32kHz, 44.1kHz, 48kHz
Input Level / Impedance / Wavelength
Optical -15dBm~-21dBm, 660nm±30nm
Coaxial 0.5Vp-p / 75 Ohm
HERE is the $199 Kenwood that offers 96kHz " 96kHz/24-bit digital-to-analog converters ensure that all your digital sources are treated right."
Read this and see what you might be able to find to help. Not sure what the costs are, but any headunit designed for A/V use should accept ALL sample rates.
Audio sample-rate converter integrates digital audio receiver, supports DVD, CD and broadcast formats.

AKM's new audio sample rate converter accepts digital audio data at 8-96KHz sample rates and converts it to another sample rate. This is particularly useful in automotive and consumer audio environments, where compatibiloity between DVD, CD and other sources is required.
New AKM Chip Simplifies Programming and Support for Consumer and Professional Audio Systems.
San Jose, California (PRWEB) August 4th, 2003 ? Asahi Kasei Microsystems Semiconductor, Inc. (AKM), a leading supplier of audio ICs for professional and consumer markets today introduced the AK4122, a 2-channel 96 kHz asynchronous sample rate converter with a built-in Digital Audio Interface (S/PDIF Receiver) for DVD, digital TV, PC and car Audio/Video applications.
The AK4122 two-channel 96 kHz Asynchronous Sample Rate Converter (SRC) that provides a combination of standard audio input ports plus a digital audio interface for DVD recorders and other audio/video equipment.
Audio is typically converted into digital data at 32KHz, 44.1KHz (CD), 48KHz, (DVD), or 96KHz (DVD-Audio) sample rates. Digital signal processors usually use a single sample rate when processing audio. In order to bridge the gap between signal processing and digital audio, sample rate converters are used. The AK4122 asynchronous sample rate converter can accept digital audio via standard DSP/I2S interfaces or S/PDIF or AES/EBU interfaces. The integration of the AES/EBU interface saves circuit board space and reduces system cost.
The AES/EBU section of the AK4122 offers the same high performance as the currently marketed AK4112B, 96kHz 24-Bit DIR including a four-input (4:1) Selector. The AK4122 can also detect non-PCM data streams like DTS and AC-3, while a CD Q subcode buffer allows the chip to easily read CD data.
The AK4122?s built-in PLL eliminates the need to provide an external master clock, and the SRC section provides two audio input ports and one output port.
Price and Availability
Available in an extremely small 48-pin LQFP package, AK4122 engineering samples are available now. The part is priced at $4.21 in 1K quantities. Evaluation boards and samples are available now directly from AKM.
