Since I don't have ArcaOS: can someone enlighten me if AN not only delivers the 10.xxx USB audio drivers (at least function wise) but also the USBAUDIF.DLL that goes with it ? You should find that DLL in the \MMOS2\DLL subdirectory.
If not I'll have to contact AN and let them know that that would be essential as this DLL and the audio drivers form a set which interacts with each other and have to match (much like USBCALLS has to match USBRESMG).

In principle, the DLL could be generic for each and every audio driver but it is messed up to the point where I decided to write my own (replacing AUDIOIF.DLL) in order not to break existing things.

Lars,

 The AN supplied file USBAUDIO-12.07.exe (which is a WPI executable) does not contain USBAUDIF.DLL, so it is not installed. I have already installed your USB audio drivers, so don't have a fresh ArcaOS installation to check...

Regards,

Remy

Does the USB 12.07 driver package WPI contain a USB audio driver or not ? What I would like to avoid is a mess where AN is delivering our drivers but not also updating/providing USBAUDIF.DLL.

Neither one WPI nor the other contains USBAUDIF.DLL.
So where does it come from?

As it is written, yours  ;)
(usbdrv234)

It was installed during test between your driver and Arca ones trying to progress Wim's webcam driver.
Those dll's have been left.

Here, it is in the usbaud2.wpi, from the ArcaOS 5.0.6.4 EN ISO.

Ok, uniaud2.wpi is fine as it contains all necessary stuff.
In short: the ArcaOS DVD contains all that is necessary but the individual WPIs for eCS/Warp customers do not.
But there will always be the option to install my USB audio drivers while keeping all the rest of the USB stack. As the USB audio drivers tend to still change even today (it's the "youngest" driver I have worked on), maybe that is the best option anyways.

I think eCS/Warp people are expected to install your packages as the readme makes clear it is third party software only included as a convenience and unsupported by Arca Noae.
It is also an option during install, in the USB section IIRC, so unless someone selects it (or later installs from the ISO), it will not be installed.

Was also wondering if the audio could be made to stream by HTTP?

Yes David, that could probably be done. I am not so sure that it would work satisfactorily since I expect delayed audio (related to video) to occur when streaming that way. Is it your intention to use HTTP streaming from webcam.exe to both wmaudio.exe and wmvideo.exe at the same time? I am asking because right now it is possible to watch the HTTP video stream using firefox or seamonkey. But in my experiments (rexx server) I was not able to do the same for audio. I could made the  browser produce the sound with the <audio> tag but alas it persisted in caching that audio rendering it useless.

 Wim,
 
Is it your intention to use HTTP streaming from webcam.exe to both wmaudio.exe and wmvideo.exe at the same time?

 Yes, I was thinking of the possibility of a simple video 'chat' setup using your programs.  Not a programmer myself, so don't know what would be involved, but I'm sure none of it is easy! (or everybody would do it). Thanks for all your efforts - much appreciated!
