In Ubuntu 8.10 Intrepid Ibex...
Open Volume Control, the microphones (all inputs) are always muted.
- Open Volume control
- Select Recording tab
- All inputs are muted
- Unmute microphone/input
- Close Volume control
- Re-open, and microphone/inputs are still muted
It seems to record anyway with some software like Sound Recorder but using Flash, there is no sound capture at all. This is happening on a Dell 1521 AMD64 (HDA-Intel card) and a Averatec 3200 32bits (VIA card).
Note: The Averactec was upgraded to 8.10 several days ago... I managed to record audio in Flash 10 by removing Pulseaudio. The I upgraded my Dell laptop 2 days ago and no succes on this one. So to compare, I went back to my Averatec, validated the sound capture was working in Flash, reinstalled Pulseaudio and "updated at the same time". Now I have no sound capture in Flash on the Averatec and the microphone cannot be unmuted like the Dell.
I did remove Pulseaudio on both computer, rebooted, configure my default sound to pulseaudio/alsa, played with .asoundrc and .asound.conf... nothing worked.
It seems that Flash is considering the muted flag and it is not impossible to broadcast thru Flash Player (blogTV, UStream).
Since it was working on my Averatec before the major update, and it does not work after the update, whatever I do, it looks like something is broken in the alsa layer.
I've looked in my logs, nothing is showing up beside this with Pulseaudio on my Dell...

EDIT: I discovered that the Volume Control (gnome applet) shows that the microphones/inputs are muted, but by monitoring with pulseaudio meter and an external microphone, they were not. The first click "unmute" the microphone (actually does nothing and the icon show unmuted) and the second click will actually mute the mic/input (validated with the Monitor of pulseaudio). But the status is always shown as muted when reloading the volume control...
The Flash player not able to record sound could be a different issue. I found out that instead of using the "pulse" plugin, it is using the "Alsa" plugin to connect to the pulseaudio server. So Flash is always trying to record using the Alsa libraries. With or without pulseaudio (ie only with Alsa), Flash 10 (in i386 or AMD64) is not able to record any sound. This state was validated on two different sound card/laptop (via and hda-intel).
Note: On the i386 (Averatec) I was able to have the Flash player output sound directly to the pulseaudio server without using the ALSA plugin, but the recording was still with the Alsa plugin and not working. I was unable to do the same on the DELL (AMD64)
I'll wait for status on this bug before reporting the Flash problem in case that the two problems are related.
