Can aswitch.exe be used for always connected/attached usb speakers?

Pete,

  Yes, you need to install the USB audio driver using Minstall. Once installed, after rebooting you should have a tab in the 'Multimedia Setup' app (in the System Setup folder) called 'USB Adapter Wave'. Make that the default Waveaudio device and sounds should come through your soundbar.

Easier:
- mount your AOS ISO
- open 'Programs\Multimedia\Multimedia Installer'
- click on "Audio Drivers on your ArcaOS DVD/ISO"
- on the dropdown list that appears, install both:
  * Enhanced USB Audio - device support
  * Enhanced USB Audio - sample rate support
  (these are from Lars' USB Audio package)

Bonus: this will also clean 'mmpm2.ini' after installation is done.

For those who want to do a cleanup without actually installing anything, select a sound driver you DO NOT have installed, then press "Install/Remove". On the next popup screen select "Remove", then OK.  It won't complain if the driver can't be found and will proceed to do cleanup, then tell you it's done.

 Hey Rich,

  That's good to know - thanks for the tip!

Hi All

Thanks for all suggestions. Sadly neither setting USB Adapter Wave as Default or using aswitch.exe work...

Yes, the soundbar works in Windows - recognised on boot without user interference.

Any other tweaks/tricks I can try?


Regards

Pete

Hi All

I may have found the cause of no sound with this usb soundbar.

I'm guessing but think the following applies:-

     usbaudio.sys supports usb1
     usbaud2.sys supports usb2
  There is no "usbaud3.sys" ie a driver to support usb3 - this is a usb3 only system, no uhci, ohci or ehci controllers.

Is the above the cause of no sound output using USB Adapter Wave as Default?


Also a guess but think that aswitch.exe only works with usb1 and usb2 as it does not work here.


Regards

Pete
