Description: Hundrends of xruns with JACK (jackit.sf.net) in fullduplex mode with snd-ca0106 (audigy se). But my onboard sound (intel-8x0) works fine. Please, do something with this annoying thing :( ====================================================================== ---------------------------------------------------------------------- sergiusz - 07-31-06 08:41 ---------------------------------------------------------------------- Exactly the same issue here, playback-only mode works.
