Beta 4 TC 0 - No audio the first few minutes

Beta4 Test candidate 0

Hardware:

HP compaq nx7000 laptop

1,4GHz Pentium M (celeron)

2Gb ram

Issue:

The system emits no sound for the first few minutes.
Discovered first with two different MP4 video files and a Wav file, subsequent tests were done only with the Wav file.
Double clicking the Wav file inmediatly after a cold boot, the file opens in MediaPlayer and starts to play but with no sound until around 2 and a half minutes (this is very consistent on several tries). Doing the same process with VLC gives more or less the same result, same with QMPlay2, except for one try that took close to 4 minutes of play for the sound to start.
Doing something else (Haikudepot, Web+, opening a folder, or simply moving a window) while the file is playing causes the progress bar and the play timer to freeze a few seconds and then advance very fast as if trying to catch up, and then freeze another few seconds, and accelerates again, etc.
This first minutes the system in general is quite sluggish, Deskbar menus takes a few seconds to appear and then just shows the outline for a few more...

Boot drive is a 4Gb partition inside a recently buyed USB2 pendrive, also tried installing and booting from a partition on internal SSD, wich I thought will do a dramatic difference, but it just reduced the time it took to start the sound to about one minute and the general sluggishness still happened, maybe a bit less.
