Default Would you pay for a Windows 24/192 driver?

Hi guys,

here is a question: would you pay +- €15 / USD21 for a Windows driver that gives you 24/192 stereo playback?

The driver cost could be an extra cost to a kit you already bought, or it could be an optional extra cost bringing the AB-1.1 from USD120 to USD141, or stand-alone USB-I2S module from USD70 to USD91.

We are looking at some licensing options, but the license must be bought in bulk for several users.


Cheers,
Børge

It would be optional, so Linux users wouldn't have to sponsor the drivers for Windows users.

From looking at the responses you have gotten here on the thread previously, I think that there would be a lot of people who would like to have a windows driver available. How many sign-ups do you need to be able to license the driver?

The Wavelength driver won't work since its focused on Gordon's products and he is paying the approx $20 ea for that driver.

The Centrance driver doesn't see it either, again they wrote it to support their devices.

I for one would support getting a custom driver (ideally one that could support all UAC2 dacs if possible) for $21.

We'd have to go to the driver vendors that Wavelength and Centrance are using.

The $21 price tag is the bare minimum of what each hardware buyer would have to pay me or George so that we could pool that money and get a driver. But such a driver would only work on hardware from one vendor. We could probably make the SDR-Widget and Audio-Widget projects appear as one vendor. Also, the driver isn't a one-time buy. It costs €1000 for every 6 months you distribute it.

Demian's ideal driver which supports all UAC2 DACs would probably not cost anything :-) The reason being that it would have to come from Microsoft or from an open source project. I'll happily voluntare to organize and test in a project like that, but unfortunately I have no experience as a driver coder.

The existing driver programmers sell one license per chip manufacturer or one license per end-equipment manufacturer.

I have asked Atmel if they would consider strapping an UAC2 driver onto our efforts, but it's been very very quiet from that front. I don't think they bother about non-iPhone music playback.

Default windows licence

Although I only use Linux, I would be happy to contribute to a group purchase to help make this more universal in application (I may also want to lend it to someone suing Windows to try)

edit: I meant 'using' not 'suing' (Is this freudian?)

This is a very interesting project! I have been looking at USB DAC solutions that operate at 24/44 with native windows drivers as a companion to an upcoming desktop version of the existing O2 Headphone Amplifier.

The ideal would be a single low cost daughter board with a USB jack and the power and line level audio connections via a pin header (getting its power from the headphone amp). The headphone amp's low noise power supply could be adapted to the DAC and analog circuitry's needs. It could use the ES9022 or another DAC. I'm thinking something like a lower cost version of this ($175 US + shipping) Tenor based board:

Violectric USB 24/96 Dac Board

The daughter board could be designed to be as "generic" as possible so it could be incorporated into other designs besides the upcoming desktop amp I'm working on (likely to be called the "ODA"--Objective Desktop Amp).

I'm curious if there's much interest in adapting this design to such a daughter board?

Default Tenor 7022L + ES9023 MiniDAC

I don't think either the AB-1.1 or my USB9023 would be a low cost fit to your hpa design. However, I was bored a few weeks ago and turned out quick board, 5cm x 5cm, using the Tenor 7022L and the ES9023 DAC. (I have attached a rendering of the pcb) I expect the circuit boards to arrive this week and will see this layout sounds.

The layout is standalone but there would be no problem adapting the design to take the supply from your HPA and feed the audio back to you.

George Boudreau
