Sound quality problem. Please help.
Firstable please bear with my poor english knowledge...
I am using a PCI128 sound card wich has an already amplified ouput connector (as well as a no amplified one) and am using the amplified one directly to my speakers (IE without external amplifier).
As a psu I have a home built Sproggy MK2 .
The problem is that the sound quality is very poor(a kind of saturation) with the BASS audio music (low audio frequencies) and it happens when increasing the volume that the speakers stop playing and here i have to reboot the pc.
One important thing : this problem is totally fixed when i use the original pc power supply (connected to the outlet).
Any help would be appreciated.
