XP sound problems

  dms_05 08:26 02 Jun 2008

I'm running XP SP3. If I play mp3 tracks through WMP all is well and I get full sound. However when I'm on the Internet (browser independent) I can't get any sound from websites. I've checked Control Panel>Sounds and Audio Devices and all the selections are correct.

My Audio Controller is a SiS7012 and the AC97 codec is ALC203. Device Manager reports all OK and a RealTek AC97 device.

Any ideas were to look next?

Right click Internet Explorer, choose properties. and scroll through the list of options to ensure that "Play Sounds" button is checked.

It is enabled. And the problem occurs with IE7, Firefox and Opera. I'm now out of any further ideas of where to look!

I've just tried a set of powered speakers and that doesn't make any difference.

So sound OK from WMP but not any other source.

Have you checked from Control Panel>Sounds and Audio Devices that your Realtek onboard sound is configured as the Default Sound Device from the Audio and Voice tabs?

Uninstall the device and it's drivers.

Download a fresh copy from:

Make sure you have the correct driver ( AC 97 OR HD)

Select the appropriate for your OS

As the sound is working OK with WMP, it's unlikely to be the drivers, although updating to the latest version won't do any harm, but configuration.

Could be worth checking that all the necessary inputs/outputs are Enabled and not Muted or the slider(s) inadvertently set on minimum, from the Volume icon on the Notification bar.

I have the latest drivers installed and all the relevant sliders are set to maximum (just in case!). Nothing is muted. WMP output is fine (and loud). My soundcard is the only one listed so no other options avilable. Very odd!

I'm going to try installinb a VoIP phone as that will generate an extra soundcard to try.........and I did but still no output via my speakers or a headset, except from WMP.

I've also dropped my Firewall to check that wasn't blocking a port. No difference with or without the Firewall.

Sound from websites is usually MIDI or Flash based, provide an example of a problematic site...

  dms_05 14:17 02 Jun 2008

Every site! No sound from any. However my Grand Daughter is specifically annoyed about click here

I'll check I have Flash loaded!
