gnome-sound-recorder fails to record from internal mic on MacBook

[Chad A Davis]

Binary package hint: gnome-media

MacBookPro6.1 with Natty (dev. branch 2011-03-26) and gnome-sound-recorder 2.32.0-0ubuntu6.

Other applications, e.g. gtk-recrordMyDesktop, record from the internal mic just fine.

gnome-volume-control also shows feedback that a signal is coming from the internal mic when speaking. gnome-sound-recorder does not pick this up, however. Rather the recording is silent, no static, nothing garbled, simply no signal at all.

That should read MacBookPro6.2 (not 6.1)

Thank you for your bug report, are you sure you selected the right input device? Did that start recently?

[Chad A Davis (chadadavis)]

Thank you for getting back to me.

I cycled through the possible input devices. Since I was testing first with gnome-sound-recorder, I assumed the sound card was simply not working correctly (for input). The MacBookPro6.2 has a few possible input devices. The gnome-volume-control has an input monitor, however. Once I saw a signal there, I decided to test another recording application. That's when I used gtk-recordMyDesktop, which recorded audio fine. Without changing the settings, I then tested gnome-sound-recorder again, knowing that my audio settings were now correct, but I got no audio from the recording, no static either, simply no signal at all.

I can't say if this is a new issue, as I hadn't tried it before. I will also be testing the natty beta that arrives this week. If you have suggestions for how I can get you better debug info, let me know.

Status changed to 'Confirmed' because the bug affects multiple users.
