Acer travelmate 3270 speakers and headphones detection problem
My laptop does not always detect external speakers or headphones. This happens when i switch on my laptop and restart it. The first time when the laptop is switched on,external speakers and headphones are detected, but the second time around they are no detected, there is no sound coming out. For speakers and headphones to be detected again, the laptop has to be switced off for atleast an hour and sometimes more time is required. This is very incovinient. What is the cause of all this? PLEASE HELP ME!!!!!

Sometimes empty/unplugged channels introduce noise to the amplifier. You can always try to connect all of the input channels to some external mobile phone/mp3 player, etc. and then set these equipments to the minimum possible volume (mute if possible). This should remove the "atmospheric" audio noise.
Computers do NOT detect speakers. Computers detect sound cards, which is the device that speakers plug in to but they are not aware of whether you are plugging in headphones, an amplifier or speakers.
The most common problems here are:
A: Your speakers are not plugged into the proper hole on the sound card. (most are color coded, make sure your cables jack color matches the color of the hole you are inserting it in.)
B: Your sound card is not installed properly. (This requires more info to resolve)
C: You volume is muted. (Instructions below)
D: Your speakers require power and are not plugged in or turned on. (Have you used these speakers before? Do they require power, is the power on?)
Go to your Control Panel under Sound and check your settings, make sure that your volume is NOT muted and that you have some sort of sound card showing.
If that does not help then please send me that Make/Model of the Computer you are using and Operating System (XP, Vista, etc) so that I may give you a specific answer with simpler instructions.
If ayou have a system with speakers that works and a different set is crackling
the set that crackles is to be determined the bad set. Cones dry up a bad assembley just coinsidents having a bad set of speakers. It is an AUDIO problem not a computer problem
go to the control pannel, then go to sounds and audio devices, then click the audio tab across the top. under sound playback, choose your speakers as the default device. solution only works like this for windows xp. good luck
hi, i recommend just using the headphone out, and it probably will not hurt the notebook, as it is not feeding back into the notebooks sound device. you may wish to do as i did, and get a creative labs external sound card. much improvement over the on-board high def sound built into my acer notebook.with all the connections you would want! as for speakers there are alot of models to pick from.i usually go with creative, but this time i went logitech- thx,dts,ect. and i am very happy. i hope this helps you make a decision on what do. good luck!glen
