USB Audio driver for AmigaOS4

Tried it with my HyperX Cloud Wireless USB headset I use for my PC and it did not work.

did you add VID and PID into prefs file? Can you send me the serial output?

@afxgroup

Thank you very much for your tireless work for Amiga!

Which prefs-file? I used the installer... I can see that there is a USB option for audio in Sound preferences. I select any of the modes and try to play a test-sound... something happens in the UI indicating that it is doing that, but I hear no sound.

EDIT: And I do not know how to do a serial output. :)

first of all copy manually from the new installer 2.2 libusb-1.library into LIBS: because the current installer doesn't overwrite it.
In the installer there is a README how to create the audio card if it is not listed in card list. But you need to know VID and PID of the audio card. And to read serial output in a console execute DumpDebugBuffer

Gave it a try with my Zoom Q2 camera in USB microphone mode.

This offers three endpoints one Class1 and 2 Class 2 . The Class 1 shows as picked by the usbaudio.fdclass in USBInspector.

In AHI prefs however it doesn't seem to work.

Occasionally it offers a device with the wrong vendor ID though I cant read all of it it start with 04 whereas the actual id is 1686, occasionally just "Front" any attempt to play the test sound with whichever output eventually locks up the SAM.

Uhm.. i didn't try any camera/wireless adapters. Just sound cards. I'll try to find something to test. BTW. You should have a serial log. Can you send it to me?

Also tried with ,y AKAI MPX16 which has a USB audio interface as USB midi.

USB inspector shows that usbaudio.usbfd has attached to the Class 1 interface and camd to the Class 3


Nothing is shown in AHI prefs. Not even non worrking options....

The ZoomQ2 can switch mode on startup. It either a webcam or a USB mic or SDCard reader when plugged in. I switched it to USB mic then rebooted. As long as the board SAM power is up it stays in the selected mode.

I will see if I can get serial logs later.

I'm probably trying fairly unconventional devices, but my only "plain" USB device is broken and doesn#t even power up.

I was able to play test beep with v2.2.. Great progress.

On Sam460.. I tried running Settlers2 game

Behringer U-Phobia UM-2.. Locks up Sound Prefs and system. No sound.

Tested using AmigaAMP, DvPlayer and Emotion.

Cheers

I can't work this weekend on audio driver since I'm working on something else. Next week I'll try to reproduce the crackling sounds.
Thank you!

@afxgroup
Another fantastic work from you, thank you so much!

I've ordered this CSL card and will do some testing with my Sam460LE once it arrives :)
