I flashed katkiss per your recommendation, and here I am, typing this from a PC, since the KB disappears on TF101 (crash?) after few letters and then reappears again. And yes, sound is still weak, and kat audio does not help at all either.
All I need is fully functional browser, wifi, video and audio - I have yet to find a custom rom that offers all this. Revolution HD as it, but due to crappy tegra 2 and lack of OC, there is no 720p video playback.
I don't think that I have faulty TF101, since stock and HD roms work just fine.
This is a known issue with the GAPPS version that you flashed... keyboard crashes (disappears) due to use of NEON instructions in the Google keyboard which the Tegra 2 lacks. Read a couple posts back for the quote.
How doe kat audio "not help at all"? It provides a slider to increase the volume level above normal.
