Yes. Both playback and recording are supported with the Lars Erdmann USB 10.234 audio drivers.

Any suggestion for audio recording software. I'm using the one includes on ArcaOS 5.0.5 (Digital Audio), but for the moment I was not able to get input audio from the USB device. (But it records from the non-USB mic input jack)

Regards

Hi Martin,

Perhaps DRECORD or DTAPE or even my own Audio Recorder to record up to 32 bit stereo at 384kHz. ?

Hi,

I purchased the UGREEN adapter (Model 30521) on Amazon which has a C-Media CM6533 chipset.  I believe it's a 2.0 device.  Linux identifies the hardware ID as 0d8c:0024.  Using the above audio drivers, I only receive white noise.  I have tried Lars' USBAUD2.SYS drivers and don't hear anything. I suspect this is a non-supported chipset.   

I see Amazon sells the Syba adapter (Model SD-CM-UAUD) that has the device ID 0D8C:0008 which Martin has identified to work. 

Neil Waldhauer:
The UGREEN unit looks like a USB audio 1. Simple mono input, low quality stereo output.

USB Audio 2.0 looks like a DJ mixing station. In fact, I think that is what most of them are used for.

Thanks for the added info. The product description referred to a "Input USB 2.0 A" but was silent on the output.  Not knowing anything about USB audio, I assumed I needed a 2.0 driver.  I'll spend more time with a 1.0 driver.  If no joy, I'll order the SYB product which states it's "USB Audio Device Class Specification 1.0" and has a vendor/device ID that has been reported by Martin to work.

I'm looking forward to finally getting sound on VMware OS/2.  I thought I was stuck with broken virtualized audio and wasn't thinking USB passthrough until I saw these recent posts on USB audio.
