Hello, I am attempting to switch to an RT kernel, but so far, I get no audio when booting one. I've tried a prebuild image from 64studio's squeeze-backports repository (2.6.33.7rt29) and also patched and built my own (2.6.33.7rt30), but the outcome is the same. The proper modules are loaded, the card shows up properly, all levels are fine in alsamixer. Jack loads without a complaint, mplayer plays a file without complaint, but there is no sound. Any one ever came up against that? Thanks, S.M.
