I always used 2.2.16 and it worked properly. Due to several reasons I want to switch to 2.4, so I tried my luck with 2.4.4-ac6. Basically it works but the sound gets interrupted (around 0.5 - 5seconds silence) from time to time although the system is around 44% idle. This never happened with 2.2.16. These interrupts are not periodically, sometimes there are none for a minute, sometimes there are even interrupts around 5 seconds long. I have to state that the data comes from an nfs-mounted directory - perhaps this is a reason? (There is no network load). Another interesting thing is that during those interrupts the processor usage of mpg123 decreases from 53% to around 20%, so it looks as if mpg123 can either not get data or not output data. Do you have any clues? Are there perhaps some kernel parameters to tune (buffer size, dma...)? Best Regards, Hermann -- ,_, (O,O) "There is more to life than increasing its speed."
