Subwoofer does not work after Win7 upgrade - Realtek ALC888

Hey everyone,

Sorry if this has been posted before, but I cannot get my sub woofer to work for the life of me in windows 7 using realtek alc888 driver.

-The subwoofer works fine in the speaker test
- Does not work when playing music from vlc/itunes/firefox

Some people have been enabling "bass management" to get it to work, but this unfortunately makes my AV40's less bassy which is not good.

Running 2 M-Audio Av40's in stereo + and old creative subwoofer


It worked fine in XP before the upgrade. I have uninstalled/reinstalled the drivers multiple times.

Seems that there is a lot of people with this issue, does anyone know a solution?

like what? I have been trying to find alternative drivers instead of the realtek ones. I downloaded the realtek ones directly from realtek and from gigabyte(my motherboard) both did not work.

hah Well if I just have 2.0 running without the sub its fine, but I find with music the AV40's needs just a LITTLE push with the bass... so yeah it kinda sucks I cant get the sub to work.

I called acer support(just to see what they'd say) and they told me microsoft has an internal article and it is a known issue... and I would also have to wait till they fix it.

Tried these drivers, unfortunately the same thing happened. Sub works when doing the speaker test, but does not work when playing music.
