I have a laptop pc -toshiba satellite pro a120- equipped with a sound card -Realtek High Definition (ALC262)-.
The problem arrived when I replaced the preinstalled operating system (which a Vista) by Windows XP and exactly when I installed the updates of Microsoft:doh: . After I have any more sound neither in the high internal speakers nor in the ear-phones. I believed at the beginning that the problem is due to the drivers thus I installed the last drivers of realtek. but without result. after I restored Windows Vista via Cd restore of toshiba. but always without any result. when I check the peripherals manager, I didn’t find any problem nor no conflicts between peripherals. I really did all that it is necessary to do but without any positive result. Thus I address to you so that you help me. especially that I lost hope and I fears that these cursed updates of Windows xp roasted the sound card.
is there a tool that can make a hardware diagnostic of the sound card chipset? beacause i think perhaps the problem is due to a an internal memory (of the sound card) issue.
OHHHHHHHHHHHHHHHHHHHH YEAAAAAAAAAAAHHHHHHHHHH !!!
Good news my friends
sound come back :D:D:D:D:D:D:D:D:D:D:D:D:D:D:D
thanks to god
i’m listenning now to beethoveen…it’s a very nice music
this is solution :
for me it’s due to a mute caused by the program of toshiba related to the specials functions keys
using fn+mute (off/on) don’t work before but when i use it with an other function key … the sound come back
so for the persons who have the same problem do this :
press fn (function key)+mute key (F1) --------> result : mute off
press fn (function key)+mute key (F1) --------> result : mute on
press then fn + lock screen key (F2) ----------> screen locked
after press Enter key -------------------------> login screen and the return of SOUND
roasted the sound card.
