Hi folks ,i have built a usb dac utilising the tda1541 chip,I have had hours of fun from it but it has developed a problem. There seems to be an annoying buzzing coming from the dac and the sound is distorted in fact now there is no sound coming from the dac. Any pointers would be most appreciated as i was liking the sound of this but am no more:(

Can you post some pics.

Where is the buzzing coming from exactly?
Do you have a volt meter?
Have you got a diagram?

Happy to help if you can provide some more info... ;)
