HP Mini 2133 is Via-based. Audio/sound works just fine.

I added atl2-module to the Alpha 6 for Eee 701. Eee 701 is Intel-based.
And now there is another bug, this time for audio.

Both mic and speakers are at full volume by default after boot, so there
is huge feedback. I do not how to decrease volume for mic. I installed
manager for pulseaudio, but it seems to do nothing in thin client.

I have never hear this kind of bug with ltsp... mic/speakers are too loud.

So if you have Intel-based laptop, try to this one. Just boot your
laptop as a thin client for Alpha 6. I tested Acer TM6592, it has same
problem - mic and speakers are at full volume > huge feedback...

Best Regards Asmo Koskinen.

Problem is here that user can't decrease or mute speakers or mic at all,
everything is all the time at full volume = feedback.

There is a opposite bug - no sound at all for ALC662.
