On a new Dell XPS 420 with Windows Vista, service tag 9sgycf1, We can hear sound in general, but we can't record sound.
Device Manager / Sound has only one device listed: SigmaTel High Definition Audio CODEC
When I run Sound Recorder, it says, 'An audio recording device cannot be found'
NOTE -- in Control Panel / Sound, Properties, the options to SHOW hidden and disconnected devices are ALREADY CHECKED. LINE IN is shown as NOT CONNECTED.
The Playback tab says:
-- Speaker, Headphones - SigmaTel High Definition Audio CODEC -- working
-- Digital Output Device (SPDIF Out) -- SigmaTel High Definition Audio CODEC --Working
But the Recording tab says:
-- Microphone -- SigmaTel High Definition Audio CODEC -- Not Plugged In
-- Line In -- SigmaTel High Definition Audio CODEC -- Not Plugged In
Back in XP, we used to use XP Souond Recorder, and switched between various inputs (mp3/wav, line in, etc) to record different things. But now in Vista we can't record anything, although everything looks ok to me in dev mgr.
I can't tell if it's a vista issue, or a limitation of the card hardware, or if its a bad card, or if I need a new driver for the card or chipset or motherboard.
