Hey,
well a few nights ago I plugged in my external monitor, there was a spark,and since then the sound has not worked on my computer.

The computer makes a boot tone when it starts up, any ideas before I send it in for warranty repair?

Thanks,
Justin.

If that's the cause then you can be certain that the damage is physical. The boot tone probably comes from an internal speaker on the motherboard, instead of the main one. I did the same thing to my onboard sound, playing with the cables of my speakers still there was a spark. PC shut down and when I turned it on, the front 2 channels were gone

Lol that sucks, the optical is connected to the onboard, so I guess it's warranty replacement time. I wonder if they will fix it...

 

[Calroth]

Should do. It failed during normal operation and you've done nothing wrong. Warranty will cover it.

I'f you haven't tried it yet, hold the F5 key down in an application in which you would normally have sound. Sometimes mine resets for no particular reason and this brings it back. Of course I've never seen sparks...

 

[juzmister]

Thanks for the help. F5 was a no go, it must be some sort of a hardware issue. I guess I will get it repaired over the break.

The boot tone comes through the internal amp and speakers. Your problem may be in the sound preference pane. Check to see if output is routed to the internal speakers.

See ya

The only output shown is headphones from the built-in output.

Try plugging and unplugging headphones a few times and see if that brings the sound back. If not, it's probably time for a service call.

See ya

you could also check Audio MIDI Setup in /applications/utilities (if this is installed on your system, i think its part of the default install, but my memory is poor...) try changing bitrate, volume, check output is set to the right thing etc.

failing that, i agree that sparks == hardware failure, hopefully they will fix it under warranty.

My girlfriend always complains about her Macbook Pro not playing sounds randomly. I think she even sent it for servicing once

I'll definitely pass this tip along, thanks!

 

[juzmister]

No speakers listed in Audio midi setup, it must have gone when the spark happened. I guess it goes to applecare over the break...

^yikes,

mine sometimes will not have sound but I usually reboot/restart to fix and recycle the system!
Wayne, I will keep your F5 trick in mind going forward for the future, hope the OP gets his PC fixed, report bac with feedback
