hello ... im a noob for sounds system ...

i just recently upgraded my PC to a decent gaming system .. ngam ngam my old 2.1 audio, something wrong with the electronics, my left speaker no sound, sometime got...

so i take this advantage of getting a new system .. budget around rm 250 ..
im looking at Logitech 5.1 Z506 .. looks nice n affordable 5.1 ..

any advice ?

one question also, Do i need to get a sound card for the 5.1 channel to work , or it can be done by software itself .. ? if need sound card, what is the difference btw expensive n cheap ... ?

thank thank !

the exact problem of te old speakers :
1. everytime i switched them on, all usb powered stuff will jerk one time... probably because of the high power required .. they shared the same extension with the PC
2. the left speaker n its wire is ok, i swapped n tested .. when i press hard on the back wooden cover (the area around the red n white RMA socket), the left speaker got back alive ...


can i use the integrated sound card from my motherboard ? it has standard pink green n blue holes...

hows the quality difference to add on sound card ? or just different in terms of function ?
my ear cant differentiate between good n best quality of sound ...

im using the speakers for gaming .. 5.1ch.. bullet shooting .. wooosshh .. must be nice ..

broken wire .. ? i dunno how to identify which wire got problem ... the wire of the left satellite speaker itself is ok, i tested it ... the problem is inside.. maybe the wire of the hole ... but inside alot of holes got many gel glues covering them .. am i suppose to remove it ?

its Eacan E-181 old 2.1 speakers ~

ya, it is damaged, when it does, the left speaker will be silent. so i swapped the left n right speaker, so that even if its damaged, the left speaker still can be tested...

very obvious fault is i need to press the back wooden cover then left speaker will become normal again ... confirm result. 100% successful rate ... but need to press kao kao hard ...

i just bought Logitech Z506 5.1 ch ... nice quality ... love it !
