Acer 5610 sound problems

Hi,

It is possible that:
1. You may have recently installed an add-on/external device such as a multimedia keyboard which changed the audio output from internal to external;
2. The laptop's internal speaker might have gone dead (highly unlikely but still a possibility) - try plugging in external speakers or a headset and check;
3. Most if not all laptops uses a female stereo babyphone jack to connect to external speakers. This jack has a built-in switch that cuts off internal speaker if an external is plug in. If you are using eternal or headset from time to time, it is possible that the switch might have locked to external and does not switch back to the internal;
4. You may have a hardware issue specifically the sound card/chipset. This of course would require an inshop repair which may be better off with an authorized service center. At worst is have the entire laptop replace if it is confirmed to be a hardware issue.

Hope this be of some help/idea. Post back how things are or should you need additional information.

Good luck and kind regards.
