I rebooted to runlevel 5. 7. I logged in using GNOME, and I looked at the sound preferences menu, in input. I found that the level indicator wasn't moving at all. 8. I tried a skype test call. It looked like it was recording my voice for 10 seconds, but when it was to play it back, it played back a NULL sequence - not 10 seconds of static, but a sequence that was 0 seconds in length. Upon further twiddling with pavucontrol, I was able to get it to work /sometimes/. I'm noticing that, upon bootup, pavucontrol lists the monitor and the input of the card among the inputs, but there is no level indicator next to the input itself. The monitor has a level indicator, but it always shows 0. I've twiddled around with killing pulseaudio, plugging in a webcam to get a second mic, turning the internal card off/on, setting it to analog output only, and so forth ... sometimes a level indicator appears underneath the input of the internal card and updates slowly. That is, the webcam's microphone's level indicator updates all the time and twitches around 75%, whereas the internal card's input's level indicator updates only about once per second. Nevertheless, when the level indicator appears, recording from the internal mic works perfectly (as tested with skype call testing service). I have no idea why one would have an input without a level indicator. I'll try to keep poking around to try and come up with a reliable way of bringing about an internal input from which I can record. Please help me if you know a sure-fire way to make this work!

[pulseaudio-discuss] Conexant CX20585 recording does not work
Hi! My mom has a laptop with the following sound card: lspci: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40) driver: snd_hda_intel alsamixer: Card: HDA ATI SB Chip: Conexant CX20585 I can't record from this card no matter what I try. It seems that alsamixer has a lot more options than pulseaudio: Mic BCapture switch Mic CCapture switch Mic ECapture switch Mic FCapture switch Capture 0% -- 100% slider Analog Mic Boost 0 db -- 40 db slider with 10 db increment Nevertheless, I will attach the output from pacmd list-sources. I have tried to record from each mic in turn, I have tried the different boost levels (0 db - 40 db), but I have had no luck picking up anything. I have attached an external mic to the line-in, but no difference. When I say I have tried to record I mean that I logged into her computer, chose one of the mics from the above list, and then I told my mom to say something while looking at the input sound level indicator in the GNOME sound settings panel. On other computers, I have found this a sufficient indication of whether the mic works. Is this inability to record a known limitation of this sound card? If not, is there some special setting I have to modify to make it work?

TIA for your help, Some mics do this weird out-of-phase thing whereby the recording level is effectively 0 when the stereo volume is synced. If you set left to say 5% and right to say 95% then it works fine. This may be the case with your h/w too. FWIW The extra options you see in ALSA are generally confusing and useless. PA attempts to consolidate it and make it a lot more user friendly. Normally you'd get a list of several port selectors in gnome-volume-control. Sadly as your card uses the incredibly helpful names of Mic B through Mic F these do not match the various standard names we probe for. David, have you come across this model on your travels? Any ideas on how we could best support it? Gabriel, if the mono trick does not help (and the model= argument to the HDA alsa module (as suggested by Dark Shadow) does not yield any results either) perhaps try using alsamixer -c0 to flip those various Mic B through F to see if any of them make things work?
