I have a 2009 Holden Barina. I turned the car on to "Accessories" and the radio was working fine. I turned the car on, and now there is a noise coming from the speakers and no music. The same thing happens with the CD player. What happened and how can I fix this?

I have edited your question to give it a more descriptive title ("repair question" applies to pretty much everything on this site), and to improve the grammar/punctuation to make it easier to read. Please check that it looks okay, and perhaps when asking future questions you could take another minute or two to proofread.– Nate EldredgeOct 3, 2014 at 14:34

Sounds like you have engine noise possibly coming through your wiring? Do you have an aftermarket audio system..?– TheJavaCoder16Mar 27, 2015 at 20:34

Start by checking the battery voltage when the car is running, if the alternator is bad it can either produce a bad voltage (too high?) which will make the radio (and possibly other electronics) behave strangely. If everything's good, I suggest you disconnect the alternator temporarily, start the car and see if the radio is still working; the alternator may be damaged and spit out poorly-rectified AC which will obviously wreak havoc and possibly damage electronics.– user5106Apr 1, 2015 at 14:35

On the face of it this should not happen. As have you white noise coming from your speakers it would seem that your radio/CD set has broken down internally. A check over from a competent auto electrician will determine if the fault is internal or down to any items such as mega-bass units external to the set, or even the aerial lead coming unplugged. A damaged external aerial could also cause this as far as the radio reception goes, but would not account for the CD not playing. Have you a set you could substitute with as a test.
Noise - means radio mode is working. Try to insert other CD, as your current CD might be damaged

Both the CD and radio is said to be working fine on the accessories key position, so it can't be that.– user5106Apr 1, 2015 at 14:31
If your car has points ignition, It may be a failed condenser. The sparking at the points creates interference, and your speaker wires could be inducting and amplifying the signals.
