GN Netcom USB Headset Outputs But Doesn't Input
Problem: New GN Netcom 2120 NC Headset connected via GN Netcom 8110 USBXP Digital Audio Adapter to my G5 2.7 Dual Processor (OS 10.4.3) has incomplete functionality:
- Earpiece works and sounds great. Can play system sounds, iTunes, etc. through it.
- Microphone works to the extent that all sound coming into it comes through the headphone's earpiece. (GN Netcom 8110 manual states "user accessible side tone which allows you to hear your own voice in the headset speaker...")
! Microphone will not input to Mac. In other words, using the Sound System Pref > Input > GN 8110 selected no sound registers on the input levels. I confirmed this by attempting to make a voice recording in QuickTime. The recording was flat / blank.
What I've tried:
- Tested on a PC to be sure hardware was functioning properly. Had complete, correct functionality. Able to make a voice recording.
- Tested headset on my PowerBook 17" 1.5ghz with same failures as G5.
Back on the G5:
- Hooked up standard audio microphone through Griffin USB iMic and was able to successfully make a voice recording.
- Tried every possible combination of input/output levels and sources in the Sound System Prefs.
- Every possible combination of selections in the Speech System Pref (Speech Recognition will not work with the microphone).
- Fooled around somewhat with Applications > Utilities > Audio MIDI Setup.
- Changed USB ports (tried keyboard, front of G5, back of G5).
- Called GN Netcom Tech Support 3X without resolution (told I needed to talk to Apple).
- Called Apple, Had me create a new user and login to that user to be sure wasn't a system problem. Same problem under new user. (told me I needed to talk to GN Netcom).
I've found very limited info on USB headsets. Most people seem to be using Bluetooth which I tried and hated. The few suggestions I did come across were "clicking and unclicking the mute button in Sound System Pref", "changing settings in Applications > Utilities > Audio MIDI Setup" and even launching Garageband (no luck with mike there either.
Other posts mentioned possible problems with CoreAudio. This seems like the likely culprit, but I need to determine if there's a solution before I return a rather expensive headset and USB adapter which I pinned a lot of hopes on for VOIP.
Any suggestions greatly appreciated.
