I have recently acquired a nice Beomaster5/Beosound5 setup with CD ripper and it's very nice.  It is not fully in use but is on my bench and I am loading music, testing functions, getting to know it, getting music tagged for good organization on this device, etc.  I have even made a clone HD with Clonezilla and now have a working backup drive in case of failure.  This forum is a great resource.

I have a Behringer UCA202 for A.AUX.  It works great, but not for the first 2-3 minutes.  For the first two minutes, there is a popping sound that comes from the audio coming from the A.AUX.  Then, after 2-3 minutes, it calms down and the audio is clear with no problems.  It is very consistent - if I go to N.MUSIC or N.RADIO for a while and then go back to A.AUX, the same popping appears again for 2 minutes or so - and actually is very much in the same rhythmic pattern each time.

Obviously the workaround is to use A.AUX and wait 2-3 minutes before streaming audio, but I would much rather fix this problem.

For troubleshooting, I have done the following: Restored the Beosound 5 and updated all software from the web to the latest version, validated the UCA202 works without audio glitches on other windows computers, checked into driver versions on XP Embedded for USB Audio Codec (windows indicates it is up to date).  I have searched all the forums I can read for a similar issue, no one is reporting it.

The only other thing I have read about is people attempting to install ASIO drivers to remove latency on the audio input to make sure 3rd party TV does not have a lip sync problem.  This is not exactly clear, I am unable to decode what is actually required here to see if this will help.  I wrote someone who tried that to ask if they ever worked it out (resolution was not posted).

Is this just me?  Plenty of people seem to use the A.AUX and none have complained of this audio glitch.  It is quiet but consistent, I'm not sure if everyone would notice.  I may try another Behringer unit, but the fact that it is not consistent always, and always goes away after 2-3 minutes makes me feel that it is something software related and I dislike throwing money at a problem before I understand it.

Can anyone:

* Confirm a similar audio glitch, or confirm that you do not have it

* Confirm if the ASIO4ALL driver or similar changed any aspect of performance on your Beosound for A.AUX?

Thank you.
