Three chirping noises, descending in tone
 

I can't use my CD burner because I am getting, at random intervals, three "chirping" noises (once one occurs, the others occur, then the system behaves for a random period of time).

These chirping noises both sound on my speakers and record into any CDs I burn, making them useless.

I've googled, and run antivirus, and cannot find that symptom.

Soundcard is good.

Any ideas?

They record into CDs? As in audio CDs?

Have you noticed anything that triggers the beeping noises?

Yes. If the tones occur during the ripping of a cd, they will play back if the rip is then played.

Likewise, if the tones occur when a (clean) rip is being burned, they will burn along with the music.

The tones occur even if no software is running, which is why I think it's a hardware or virus issue. Since i have no problems with my sound card, I am assuming it is a virus. Virus scans and the like show no indication of that, however.

The tones do occur more frequently with heavy CPU use, but I cannot narrow it down to once-every-X-cycles or such.

What software are you using to burn these cds?

I'm honestly stumped as to how a stream of digital data would be corrupted when burning or ripping a CD. If you play an audio file during a burn or rip, is the resultant datafile likewise corrupted?

As in playing Song A from a file on my Computer while burning or ripping song B from/to disk, will A be affected?

I'll have to experiment with that. B will be affected. I will try that and replay A after the tones occur to see if A is affected also.

OS is Fedora Core 4.

I don't mean affected by the beeps, but will B contain part of A? I'm trying to figure out how this is even possible.

Ah, sorry.

No, B did not contain A.

Also, I found the solution. Seems that when the antivirus/firewall (ClamAV modified by a friend) thinks it detects communication to/from internet, it was supposed to sound those tones as an alarm/indicator. Rather than just send the tones to the speakers, however, they are sent through the system in such a way as to use the sound card and whatever else is used by the CD rip/burn programs. Disabled the tone warning and now no interference.

Situation presented itself because I had accidently activated the audio warning and did not connect the two occurances mentally. Sigh. The mind is the second to go.

Thanks.
