How about reading the last sentence in the error message?

I'm not the OP, but I have this same problem. The only audio error I'm seeing in the logs is concerning opening up the input devices(mic and line-in). I don't understand why it's trying to open these exclusively anyway.

00:00:03.905 Audio: Trying driver 'dsound'.
00:00:04.014 DSound: Could not initialize DirectSoundCapture
00:00:04.016 Audio: set_record_source ars=0 als=0 (not implemented)
00:00:04.017 AC97: WARNING: Unable to open PCM IN!
00:00:04.017 AC97: WARNING: Unable to open PCM MC!
00:00:04.017 VM: Raising runtime error 'HostAudioNotResponding' (fFlags=0x0)
00:00:04.017 Console: VM runtime error: fatal=false, errorID=HostAudioNotResponding message="Some audio devices (PCM_in, PCM_mic) could not be opened. Guest applications generating audio output or depending on audio input may hang. Make sure your host audio device is working properly. Check the logfile for error messages of the audio subsystem"


I've tried enabling and disabling exclusive access to the sound card in Windows 7 as well as running VirtualBox as an administrator. Nothing I've tried gets rid of this issue

I did not have this before 4.0.10... but since upgraded to 4.0.10 I am having this error too on my existing machines that were working fine.
upgraded now to 4.0.12 and still having this error. so I have no idea.
However... I can listen to guest sounds... so I don't know what this warning means.

I have the exact same problem and same error message
running Virtual Box 4.1.0, this is my first installation. Windows 7 Professional host OS, Windows 98 guest.
Tried installing the Guest Additions but received an error that they will not install on this version of windows (not sure if that referred to host or guest OS!)

thanks for any clues

I have seen this error very long time always when starting any guest on my W7 host. The log shows similar as shown in one of the previous messages.

I solved my problem this way:

I plugged my headphones + microphone onto the computer (there was none before) and now I do not see the error anymore!
