[Pulseaudio] Microphone from the webcam is not working on Vaio S

Hi All !

After years using Arch I'm facing a dumb issue: my webcam's microphone is not working.

I just installed Arch on my brand new Vaio S (VJS131X0211B) and everything went well except this microphone issue. I installed pulseaudio for the first time in my life because I plan to use the bluetooth so maybe I made a mistake at that point.

I followed the instructions from the wiki to install pulseaudio and using ponymix I switched the source to my microphone (confirmed with the output of arecord -l). I then tried to record something with arecord -d 5 /tmp/test.wav but when I listened to the file I only heard background noise. I solved the issue by resampling the sound as described in the wiki and I also added the Echo/Noise cancellation option.
Now when I listen to new record I have no sound at all. Of course, I checked that all my channels are unmute and I put their volume to the max.

Ideas?
Thanks.

PS: I also have a jack plug but I don't think it can mess anything up because I only have one sound card (a classic Intel HD Audio). Also the output is working since I can listen to any other sound on my computer.

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

arecord utilizes the ALSA API and whatever you attempt to do there doesn't necessarily reflect how the devices are set up in pulseaudio. Post 

pacmd list-cards
pacmd list-sources
pacmd list-source-outputs #While recording something

in [ code ] tags, there's a good chance that the echo-cancel-module you loaded has defaulted to the wrong source, see here for configuration options: module-echo-cancel you will likely want to at least set the source_master correctly. But if you provide those outputs I requested I can help you with diagnosing this further

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

I don't have my laptop with me right now, I will give you the output of the commands tonight. I did not know the last one that should help me.

I was using arecord -l as a "confirmation" of my pulseaudio setup. Actually I do all my sound configuration through ponymix (same thing as pacmd).
Since I am using pulseaudio, is there any other "better" command than arecord to use to record a sound?

Thanks for your help.

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

arecord -l queries ALSA devices, it doesn't reflect pulse's usage of them. At most aplay -L could be used to verify that you have a "default" PCM which points to pulseaudio via the ALSA plugin. If that is the case, arecord can be used for recording and can be manipulated using the usual pulseaudio tools (e.g. pavucontrol) for more specialized control pulseaudio provides the parec utility which allows some more fine grained control and use of pulse's features (e.g. only record the output from a specific application without other potential interfering sounds). but to properly use parec you will have to refer to the info from the pacmd commands.

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

I never used pulseaudio before and only use it now because alsa does not manage the bluetooth. I have so much to learn about pulseaudio...
I understand that alsa and pulseaudio are not the same thing and their tools cannot be used to verify the input/output used by the other. I was just using arecord -l to list the output in addition to ponymix list and make sure I did not miss any before configuring pulseaudio using ponymix. That's just my useless paranoid verification ^^

I will come back to you with all the outputs tonight.

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

Is that useful?
With my limited knowledge I do not see anything wrong in these outputs. It seems to me that the active source is the one used to record my sound but I cannot hear any sound from my recorded file. What am I missing?

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

Apparently this does not help sad sad sad
It's really bad and frustrating because this microphone issue is the only one I have and it's really annoying to not be able to communicate with my friends.

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

The channel map is somewhat weird, the name as well, see my link for additional configuration (and imho you should first make sure that the not echo cancelled input works, did you try that because you noticed many background noises or just "because"?) the actual microphone source is ls alsa_input.pci-0000_00_1f.3.analog-stereo so switch the microphone sink to that to check if it works. (or use 

pacmd set-default-source alsa_input.pci-0000_00_1f.3.analog-stereo
pacmd move-source-output $SOURCEINDEX alsa_input.pci-0000_00_1f.3.analog-stereo # replace $SOURCEINDEX with the index of whatever you attempt to record from from pacmd list-source-outputs

I will try to set up a echo-cancel module tonight or tomorrow on my rig and get back to you if I find something more, could you post your /etc/pulse/default.pa so that we can check your current configuration?

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

Thanks for coming back. I tried the echo canceled in the first place because of background noises as I said but now I removed it to "simplify" things.
Why the channel map and name are weird? I did not do anything to change that and the laptop is brand new. What did you see that is not expected? I never used pulseaudio before so I'm completely lost.

I tried your commands and recorded a sound but the file is still "empty" (only background noise). I will not have time to go deeper this week-end but I will come back early next week. In the meantime here is my default.pa (moved to my home directory as suggested in the wiki):

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

There we have the culprit of the weird name, you manually load an alsa-sink  (AND the echo cancel module acted on the HDMI output which definitely is not going to work). There's really not much reason to do that, pulse creates the correct devices with the udev load automatically, remove that line (except if that does allow you to play back something via speakers and hdmi simultaneously and that was your reason for loading it, you could also keep it). Also tsched=0 is a misguided "fix" in most cases necessary to work around broken drivers, most of the issues with that have been fixed long ago, there's really no need to use that with a well supported realtek card. After having done these changes, can you repost the 

pacmd list-sources
pacmd list-source-outputs

and the exact commands you are attempting to use to record something? One thing we might want to try, is if the jack input is misdetected is to use 

pacmd set-source-port  alsa_input.pci-0000_00_1f.3.analog-stereo analog-input-internal-mic

to force it to use the other jack, maybe the default detection is flaky here.

Thanks for helping. I manually loaded an alsa-sink because, if not, my HDMI output is not recognized as shown with the new outputs with this default.pa:

After pacmd set-source-port  alsa_input.pci-0000_00_1f.3.analog-stereo analog-input-internal-mic and a new record I (maybe) have less background noise but that is it.

I am so bad with this configuration...

PS: the alsamixer screenshot if it can help.

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

Lower your capture volume in pavucontrol, it might overdrive and not really be necessary to be that high. You don't want your HDMI to be a source (a recording device), sinks (an output device) can be queried with 

pacmd list-sinks

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

Sorry, you're right. I added my HDMI as a sink and in the same post I'm talking about sources... I slept 3 hours last night so I get confused.
My HDMI is not listed as a sink and that is why I manually loaded it as a sink:

I tried with different capture levels between 20% and 70% but nothing changed...

I noticed that my internal microphone state is "unplugged" whatever I'm doing through pacmd...

EDIT:
I don't know if it can help but I can get rid of the "unplugged" state of the internal microphone if I put this in my /etc/modprobe.d/snd-hda-intel.conf

options snd-hda-intel model=laptop-amic

But it does not change anything to my recording tests. The issue remains.

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

There are 4 mic controls present in your alsamixer screenshot, have you played around with reduced values for all of them? I don't think pulse's control will manipulate those "internal mic boosts" you have to do that in alsamixer yourself.

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

Now I'm running out of options as well let's go a bit deeper, anything in 

dmesg
journalctl --user-unit=pulseaudio

? You might want to see if it is a driver issue with the kernel and try linux-lts for example

Another thing, you mentioned you had changed the sample rate, what did you change it to and does it work if you reflect those changes in parec?

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

I removed the change made to the sample rate. I first made it to "correct" the static noise.
Here are the outputs:

I do not really understand the error "Sink alsa_output.pci-0000_00_1f.3.analog-stereo". I can hear sound and this output is listed and used as shown with the pacmd list-sinks command.

Re: [Pulseaudio] Microphone from the webcam is not working on Vaio S

Just tried with an external mic and everything is working... But my external mic is recognized as the internal mic in pavucontrol.
So maybe the real issue is that my internal mic is not recognized as it should be. Any idea how to correct this?
