Does Realtek ALC887 sound chip not support Stereo Mix?

On my ASUS H81M-A, simultaneous recording of sounds produced by speakers and received by a microphone is impossible with any software.
The on-board sound chip is Realtek ALC887. Does it not support Stereo Mix?

Are you using your Asus Al Suite 11 to enable special features? Neil.

 

What special features should I enable? I do not use ASUS AI Suite 3 at all.

 

Have you got a stereo plug/s on your mic cable?
See this:https://www.google.co.nz/search?q=Stereo+plugs&tbm=isch&tbo=u&source=univ&sa=X&ei=FihZVa_WOqO6mAXzsIHQDg&ved=0CCcQsAQ&biw=1920&bih=946
Just a thought that you may have incorrect/faulty connectors. Neil.

I use the above mic, which has only one plug, which is 3.5mm stereo.
On my old computer, i.e. eMachines EL1850, simultaneous recording was possible with this mic, so I think the problem does not lie in it.

 

I would hope so!

Understand you are talking about a feedback loop. This happens when the mic picks up the sound from your speakers, then re-amplifies it causing a loop. The mic then picks it up again, and amplifies it again, then again, then again - until the amplifier, speakers or your ears blow.

Better amps are designed to protect themselves from such overloads, but the speakers may not be.

"Stereo Mix" does NOT take the audio "output from" your speakers. It takes the audio "input to" your speakers and mixes it with the microphone's output.

With that, I hope now we are on the same page. See if this helps.

 

I am not talking about a feedback loop. On my old computer, I used earpieces and a mic, which picked up no sounds from the earpieces. However, simultaneous recording was still possible, for example a conversation on Skype. Now it is impossible. Why?

 

Right, because that's different from what you said earlier. A mic cannot pick up sound produced by the earpieces. But a mic can pick up sound produced by regular speakers if the speaker output is loud enough, or the mic is too close to the speaker.

You may not have meant feedback loop, but when you said, "simultaneous recording of sounds produced by speakers and received by a microphone ", feedback loop is exactly what you described.

By "now" do you mean when using your earphones?

Did you follow the link in my last post?

 

Sorry for the wrong wording. 'Sounds produced by speakers' should actually be 'audio input to speakers'.

I mean using my earpieces on my present computer, ASUS H81M-A, instead of the old one, eMachines EL1850.

My Stereo Mix has long been enabled. I can separately record audio input to speakers/earpieces and sounds received by the mic, but not simultaneously, which was possible on my old computer.

Off topic: Can the adverb 'simultaneously' be grammatically used as the antecedent of the relative pronoun 'which'?

 

OT first - if asking about the first sentence above, yes, it is grammatically correct.

Are you sure you didn't have a 3rd party application installed on your old computer? Maybe you need to tell us exactly what you are trying to record. I note to record both sides of a conversation (like with Skype) see this.

 

On my old computer, I could record Skype conversations using Windows Sound Recorder.
On my present computer, I failed to do so using Windows Sound Recorder and Audacity Portable.

 

Your Audacity link goes to something else. Did you mean Audacity?

I am afraid I don't know what is wrong here. Hopefully someone else will have some ideas, or you might post your question via SourceForge Support.

I suspect the problem lies in my sound chip instead of the software.
