All of a sudden my Insignia TV sounds tinny with an echo. I have a soundbar, and it doesn't change whether I have it on or off? I've re-set the audio to the factory settings, and it did not help. Any ideas on how to fix this bothersome issue would be appreciated.

I have also had an acer aspire notebook for about a month too. I have had several problems including sound ones and have contacted the acer helpdesk. I have had excellent help and service each time from them and problems have been solved quickly and easily. Tel:- 08708 531000

i have hp dv5000 as well. and i had the same problem.
what helped me is that:
you go to start - control panel - administrative tools -
then take: device manager.
in the device manager window you click on the plus near:
IDE ATA/ATAPI controllers
right click on: primery IDE channel
and select uinstall.
at that moment you will probably feel that the computer is back to its speed. restart anyway.
it will tell you new hardwear found, click: ok to everything it will install the primery IDE chenell again.
well that worked for me...

try to introduce your speaker one by one and check every time you enter the speaker check for bad cable(internel short)open cable cover and touching of adjacent cables together.-try to change the position of your speakers.

Make sure you have the tv volume turned right down as this will cause an echo,also set amp to prologic 2, and set up xover to suit your speakers or go for the THX standard of 80 hrtz and as a rule of thumb set front L,C,R speakers to zero rears to about +4or5 and your sub to -5[ dont know which speakers you have but try setting the subs on board volume to the 10,o,cloak position],also make sure the speakers -,+ are wired the same at the amp and speakers.

Hope this helps.
