m4400 sound isses!

Guys,can someone give me step-by-step instructions how to resolve audio issues?I tried contacting dell on this,but they couldn't offer anything except of speaker replacement!

EDIT: I know that there are lots of threads about this,but I couldn't find any instructions!

 

Hey Xirurg,

download dpc latency checker and tell me what the results are.
If you get constant red spikes, go into your BIOS and disable your modular bay (DVD) You can also just slide the DVD itself out.
If that doesn't help, try disabling your LAN first...after that the WLAN. While doing this keep an eye on the reading of DPC latency checker, it should go into the green area.

 

Downloaded!it is 8000-16000

 

ok,when i remove dvd,it goes to green/yellow!

EDITk,so i figured it out! w/o dvd and WLAN,it is all green!with WLAN,w/o dvd it is mix of green,red and yellow!So what should i do to fix this?

 

Did you try switching off LAN and DVD but keep WLAN on? If it's the WLAN bugging then i don't really know a fix.....with me it's the LAN and i don't really mind keeping that disabled 'cause i never use it anyway

 

interesting.. I wonder if this is the cause of my audio stuttering problems?
latency check shows a pattern of red green green green red, etc. basically lots of red here and there with green in between.

 

with WLAN but w/o dvd and lan i get a mix of green yellow and red.it should be green always?

 

a little update!if i uninstall dvd,it is still red,when i remove it it goes to green.

 

Dont uninstall it!! ....disable modular Bay in BIOS, which IS the DVD or remove the drive physically

 

so the fix is removing DVD?
