I have playback "skips" on my X-Fi soundcard (chipsetĀ EMU20K2), under Linux 2.6.39.
When playing audio or video files, sometimes the playback jumps skipping about a second of the file.

This happens with many applications, using ALSA as audio output driver.

I tried running mplayer from the console and I have this message when a skip occurs:
"Increasing filtered audio buffer size from 65536 to 67536."

Where could be my problem? Please let me know if you need more information about my system.
