Hello everyone,
My laptop is Acer Aspire TimelineX 4820TG with Switchable Graphics ATI/Intel. I disabled ATI when boot by adding this line to /etc/init.d/boot.local
However, KMix determined two Analog Stereo
![]()
But only the left Stereo affects the sound of system, the right is no use at all (I tried headphones or other sound devices but it didn't control anything).
Moreover, sometime I reboot and choose Windows 7 Home Premium for some reasons. The internal speakers work as usual but the external speakers and headphones don't work. I come back to openSUSE and everything work fine. Then I choose Windows for next boot, these devices continues to work!
I realize this problem SOMETIMES occured, but it only occured when the previous boot was openSUSE. Did I do anything wrong to KMix?
Hope for your help.
THanks a lot.
P/S: Sorry for my bad English.
