When i play any audio on the PC and without anything plugged into the sound jack front or back, the sound is played through the on board PC speaker. If i plug headphones or speakers into either of the sound jacks the sound is played through the new speakers BUT it also continues to play through the PC speaker. This is fine when using speakers but not when using headphones as others can still hear the audio.
My understanding is that when either headphones or speakers are plugged into the onboard soundcard (front or back) the sound should be diverted to the new device and no sound should come from the PC speaker.
Ive looked at the following with no apparent change
In the Bios - disabled the system Beep (this does exactly that and not the PC speaker)
In the Bios - disabled the soundcard (this does exactly that and disables ALL sound from the card)
In Windows Divice Manager - disabled the system speaker (this had no effect at all)
I may have tried a few other things relating to audio settings but so far nothing has stopped the audio from comming out of the PC speaker EXCEPT pulling the power cable from the speaker itself.
