@LiveForIt

I have the MD datatype already.. I have to release it..

Yes it is

@hotrod

IIRC it is on OS4depot but I don't remember the name and I don't think there are themes only for betatesters

@Capehill

With latest clib4 (development branch) you should be able to clone scummvm without any problem but.
1) use --depth 1 otherwise you could have problems since there are 1.5millions of objects and it will took ages
2) I have only an encoding problem on 1 file




In any case I'm trying to port the last master version.

@Djk83

Thank you for your reports. I can work on the drivers (and all other stuff i'm working on) in a few weeks.
Unfortunately my real work is filling up all my free time..

@TSK

Can you send me the serial log? and which audio card you have (and maybe also the machine you are using)

@smarkusg

It seems correct. The only problem seems:

Start: SET_CUR sample rate failed: -9

But this is not a qemu problem.
I will investigate

Check that libraries are copied correctly over the old one.. Just in case.
And test also all audio modes.
And remember me which machine are you using

A new driver is available (version 2.3). You should be able to play correctly now on almost all platforms. Changelog:

BOOT SAFETY
------------

The driver is safe to have installed with a USB audio device permanently
connected. All USB access is deferred until the first actual playback
request (AHIsub_AllocAudio). Before scanning, the driver waits for the
Sirion USB stack to signal USBNM_TYPE_STACKFULLBOOTED, ensuring the
stack has fully initialised and all USB function drivers have completed
their setup. A 5-second timeout prevents indefinite hangs if the stack
was already booted before the notification subscription.


CONCURRENT ACCESS
-----------------

USB audio is exclusive: only one playback stream can use the isochronous
endpoint at a time. If another application (e.g. a music player) is
already playing through the USB audio device, a new AHI session (e.g.
AHI Prefs test tone) will be refused gracefully — the running playback
is never interrupted.


DEVICE HOT-REMOVAL
------------------

If the USB audio device is physically unplugged during playback or
recording, the driver detects the loss (consecutive fatal USB errors)
and stops the playback/recording process cleanly. No system hang or
crash will occur.


There are some problems on Input and Output but I think this is because the USBAUDIO audio mode that should be generated at runtime. I will check this.
Enjoy

@Maijestro

Can you try the latest development branch?

@Maijestro

Thank you for the update. Just one question. Which clib4 version are you using?

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!

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?

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

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

I updated the driver to version 2.2 (you can always download it from ko-fi).
This version also includes a usbfd that allows AHI to be updated transparently when connecting/disconnecting devices.
Therefore, it's not necessary to run AddAudioModes; everything is done transparently.
Thanks for the feedback and appreciation.

I've updated the Ko-Fi page with a new dirver (version 2.1)

At moment in the driver I have these audio cards:

0D8C:0102 USB Audio (0D8C:0102) [C-Media CM106]
0D8C:013C C-Media CM108
0D8C:000C C-Media Audio
0D8C:0014 Unitek Y-247A
041E:324D Creative Sound Blaster Play! 3
1B3F:2008 GeneralPlus USB Audio
1130:F211 Tenx TP6911 Headset

Use USBAudio.prefs if you want to use an unlisted card

This is working: https://www.amazon.it/dp/B002LM0U2S
And also this one: https://www.amazon.it/CSL-Ingresso-Mic ... nd-funzione/dp/B00NXV4NPQ

But should work also something like this:

@Maijestro

All libraries are on OS4depot with clib4 version included

I've been building a native USB Audio Class driver for AmigaOS 4 from scratch. It now supports stereo playback, 7.1 multichannel surround, recording with input switching, multi-device detection, and user-configurable device names. It's in beta

What works:

- Stereo and 7.1 multichannel playback
- Recording with Microphone, Line In, and SPDIF input switching
- Hardware volume control and input gain
- Multiple USB audio device detection and selection
- Glitch-free playback with triple-buffered isochronous transfers
- Clean start/stop without crashes
- Custom device names via prefs file
- Amiga Installer package for easy deployment

What to be aware of (beta caveats):

- Only USB Audio Class 1.0 devices are supported (covers most USB sound cards)
- Only 16-bit PCM format is currently handled
- The device must be connected before AHI initializes the driver
- Hot-plug/unplug while audio is playing will cause issues
- Not all USB audio devices have been tested — your mileage may vary
- Recording quality and input switching behavior depends on the specific USB chipsetIf you encounter problems, please capture the full serial debug log (all lines starting with [USBAudio]) and report the issue along with your device's VID:PID.

I'll add on os4 depot once it is stable enough
