They have the assumption that sound cards are still simple devices with one input jack and one output jack and any application using it just has to find the sound card and output its audio signal. It's not as simple as that anymore. Modern audio codecs have tons of options and volume controls, and - from my experience - most problems to PulseAudio relate to the sound card being incorrectly configured. To resolve this problem, people then try to use tools like alsamixer and naturally, since alsamixer doesn't know anything about PulseAudio, it cannot fully configure it. So, in order to be able to properly configure PulseAudio, install "pavucontrol" or use the sound preferences in GNOME3 or MATE (with the package mate-media-pulse being installed). Then run pavucontrol or the MATE/GNOME sound preferences and make sure that: * the proper sound card has been selected (it might be set to HDMI audio if your graphics card has HDMI) * the proper sound output/input you want to use is selected and not muted * the sound card is set to Analog Duplex Stereo When using MATE, make sure you are actually the PulseAudio control panel, not the old ALSA-type one, those are not the same. There are some pitfalls when using PulseAudio and expecting it to behave exactly like plain ALSA. PulseAudio provides much more features and possible configuration settings, so one has to be sure to get these right. I also highly recommend asking in the #pulse-audio channel on FreeNode (if I remember that that was the proper name of the channel). Those people are awesome and it usually takes a few minutes and you have your problem resolved. Adrian -- .''`.
