With 2.4.10-pre10 I noticed alsaplayer skiping once or twice the skips shouldn't really be realated to vm changes, if something to the schedrt fix. but the real issue is that you should avoid to run top at -10 (or you meant +10?). Running top at -10 isn't a good idea, it is allowing it to get more cpu than the other tasks for no good reason. Andrea
