Any way of getting audio to work on modern hardware?

It seems that ROS does not support any modern HD audio right now? Driver installation got stuck at 100% CPU load when trying to install drivers on my ThinkPad T430(s).

Is there any known way to get audio? I did get it to run on my old ThinkPad T23 with the Windows drivers but that is a vintage system.

I am talking about a laptop (T410 or T430(s)) so it would have to be a usb device using vgal's usb-patches.

Audio support is still experimental and can cause bugs, so you better try it out on a VM.

AC97 sort of works, HD audio does not as you already realized by testing. So right now your only way is a VM emulating you a AC97 device. Audio is not top priority right now I fear.

It is surprisingly difficult to find an older USB AC97 sound card, maybe these were never produced bc that technology was on every board?

However I did find this, maybe I should give it a try :D

Edit: might be same as this:

Drivers not needed from Win98SE to Vista indicates AC97 instead of HDaudio

My newest computer with AC97 is a ThinkPad T43p from 2005 with a single core Pentium-M, already a vintage machine. The following T60 had HD audio.

So I have ordered one of these USB audio cards for 1.5€ from China, let's see how that works out :D

I doubt that it will work due to isochronous transfer support missing in usb host drivers (usbehci / usbohci / usbuhci) and missing stream pointer api in ks
