How to get sound from the laptop speakers -and- headphones at the same time

2010-09-28, 21:13 PM

I would like to have the sound outputted from the laptop speakers, and also a stereo soundbar connected to the headphone jack.

The soundbar has lower pitches and more fullness, while the laptop speakers have better sound in the higher ranges.

This is related information...

 

I have a T500 (20823HU), with Conexant 20561 SmartAudio HD, driver 3.64.12.0.

 

 

Outputting audio to the internal speakers and external jack simultaneously is called MultiStream Mode on the conexant smartaudio HD.

swg101 (All),

 

As you had earlier indicated you were running Vista Ult 32, your Win 7 post above suggests that Conexant's CX20561 does in fact support the Audio Director functions of SmartAudio II under Vista and that it had worked properly for you.

 

 

Do Audio Director services actually appear and operate in Vista 32?

 

 

From Conexant's SmartAudio II Help file:

 

Classic mode emulates the behavior of Microsoft Windows XP, where sound is heard either on the speakers or on the headphones, but not both at the same time. To select Classic mode, click on the corresponding icon.

 

In Multi-Stream mode, different sounds can be played on speakers and headphones simultaneously. To select Multi-Stream mode, click on the corresponding icon.

 

If so, folks should know that Conexant's driver package does not install these features in Win XP. The Audio Director icon is not presented by the SmartAudio II control center in these systems; only the Volume Mixer, Voice Effects and SmartEQ / 3D Settings are available. Have not explored the operation of Conexant driver packages under Vista, so had suggested in an earlier post that the Audio Director feature-set seemed to be unavailable to the CX20561 audio chipset deployed in ThinkPads. Thus, based on your current post, this may not actually be the case.

 

Frankly, there's no good reason these functions should operate in Vista and not in XP. If the hardware supports an audio function, it simply becomes a feature-deployment decision as to setting it up in Vista vs XP. A guess is that the developer may have assumed many XP systems were wimpy and chose to minimize user disappointment (heh) and limit support calls by withholding the feature from XP and enabling it on "more robust" systems running Vista. Bad call (see "Kool-Aid").

 

If this theory is correct, we may be able to hack the setup and provide Conexant's Audio Director features for XP users. (Their practical value, however, is a different matter...)

 

To start, could we ask you to try to identify and find the 32-bit .dll that contains the library for the Audio Director functions? If you can do this and post the .dll, we can attempt to get it to fire up under Win XP. Down the road, other procedures may be appropriate.
