Check your setup - is the connection plugged in securely and correctly?.Not much reading involved.If you have plugged your headset into a USB port, and after several minutes the device is not recognized in the system or showing up in your applications, please try the following to see if it is a connection issue rather than problems with your hardware: These commands are well named, so you will know what each does immediately. Man pactl and man pacmd will have all of the commands you need. However, without a way to tell what the issue is, I can only give you the tools. If you can provide a venue to post the output to pactl list cards, pactl list sources, and pactl list sink-inputs, I can walk you through the process. pactl is supposed to be a front-end for pacmd, but in my experience, they are pretty much the same save for slightly different syntax and the fact that pacmd can do a few things that pactl cannot. Both of these use the same objects that I described above. If you would rather work with the command line, you can use pacmd or pactl. It mostly focuses on sharing streams over the internal network. This app doesn't really help in the current situation, but it does give extra capabilities to pulseaudio. In your case, (although it is hard to tell without any console output) it sounds like you may have a stream without a sink. Paprefs lets you configure streams with actions such as moving them from one sink to another, etc. If you know what these are, you can configure pulseaudio from pretty much any CLI or GUI. The Four main words in parentheses above are the keywords that make up the entire pulseaudio abstraction. Audacity or another audio / streaming app.) Your mic will ideally stream audio from Alsa (Source) into the stream (Source-Input) and at the other end of the stream (Sink-Input) it will feed into its output / destination (Sink, e.g. Think of a stream as a pipe, but for sound. This app will let you configure pa streams. This is short for Pulseaudio Preferences. Since you have nowhere to post command line output, I will recommend 2 pulseaudio gui packages that will get you up and running. Once again, if you see your device model name, you're good. You're good.Īlternatively, when you run the command that I included in my comment, or the one from above look through the names of all the device.\* entries. If this command gives the name of your headphones in its output then don't worry about Google. Once you find the recommended, check that against the results of lsmod | grep Audio. It may be called an "audio card", "Device Driver", or similar. Getting the first two from your specs, and the first few results should contain something (at least close to) official from launchpad,, etc. This doesn't mean that it is the correct driver. Otherwise Pulseaudio would not be detecting it. You can check pactl list cards to be sure, but I guarantee that your device is linked to a driver. As I said, there are other features, i.e the ins / outs, etc., but these mostly facilitate the main duties listed above. Alsa is a driver database (among other things) whose job it is to connect your hardware with the proper "sound card" which actually refers to, again, a driver that provides access to that hardware (the physical sound card for which the alsa "sound card" is an abstraction.) It is more or less responsible for getting your hardware properly mapped into udev. I do not believe that alsa is your problem. Any hing how to progress on this? What's the respective roles of pulseaudio, pavucontrol, alsamixer? I tried this: /title/PulseAudio/… but Alsamixer interface is obscure. On my computer, the microphone sound is correctly detected in pavucontrol, but it's marked as unplugged and not present in audio parameters. As the question will disappear along with the bounty, I will include it, word for word, below, in hopes that it can be somewhat useful to users in the future. ![]() This answer is to a question provided via a separate user's bounty of this question.
