Hi all, I have recently bought a SONY HT-SS380 Home Theatre, and I tried to connect it to my Acer Aspire 5552-5686 through HDMI port. (I have Windows 7).

My problem is that I can´t configure the laptop to use more than 2 channels (stereo). I´ve been looking around in internet and it seems to be a usual problem with this computer, but I can´t understand why, or how to fix it.

I´ve tried to install the last Realtek Audio drivers, the Catalyst Control Center, some HDMI Audio drivers from ATI. I don´t know what else to try!!

Any help?

Thanks a lot!

I would like to understand why you are expecting 5.1 Surround on this platform.

Is there something indicating that it should support it?

I'm seeing that the audio chipset is Realtek ALC272.

Specs for that chipset are here:

All of the specs for that chipset seem to indicate stereo playback.

But I´m connecting my Home Theatre to the HDMI port of the ATI Mobility Radeon HD 4250.

And in the specs af this card:

• HDMI® output support
• Supports all display resolutions up to 1920x10801
• Integrated HD audio controller with multi-channel (5.1) AC3 support, enabling a plug-and-play cable-less audio solution

What do you think?

That's not the audio chipset of this system, as I listed above.

The audio chipset must be sending the data in 5.1 surround.  The HDMI port would support it, if it were being sent.

It's not being sent that way, as I listed above.
