| + | **How to load?**\\ | ||
| + | Way 1 kill pulseaudio, modify default.pa to name new module, restart PA\\ | ||
| + | Way 2 (more suitable for command line users)\\ | ||
| + | * Open terminal | ||
| + | * pacmd (name of command to type press enter) | ||
| + | * help (pacmd has a help page but for us try | ||
| + | * load-module module-name eg | ||
| + | < | ||
| + | pacmd | ||
| + | load-module module-switch-on-port-available | ||
| + | </ | ||
| + | |||
| + | If module succeeds you get no feedback, but if it fails you see **Module load failed**. | ||

| + | =====PA controls sound device issues===== | ||
| + | If you have pavucontrol open, then PA controls your device and won't release. This impacts on microphone testing of arecord as per alsa wiki.\\ | ||
| + | Solution close down all pavucontrol and paprefs and wait about 10 seconds and try again. | ||
| + | |||
| + | You know PA has control when you see an error like this | ||
| + | < | ||
| + | arecord -d 20 -f dat / | ||
| + | ALSA lib pcm_dsnoop.c: | ||
| + | arecord: main:660: audio open error: Device or resource busy | ||

| + | |||
| + | Now I have deliberately shown a naughty image. I have raised volumes higher than my hardware can do. This proves PA is a post-processor and is a warning do not have volumes set this high....you will have distortion. | ||
| + | |||
| + | Now I reset the volume for me around 80% | ||
| + | |||
| + | Now if your voice on playback has sufficient volume then one issue is resolved. But you can have machine hum. This may be easy to resolve by having your mic input as far away as possible from any fan noise. (B) If you can, consider reducing any fan speeds on your pc. | ||
