Problems with Audio Recording

[wonder]

Seems like you set the input volume too high so it gets only distorted sound.

Not, because in windows, with the same volume works fine.
And in linux, I don't listen the audio by line in (in windows yes).

Can you check the settings or recording again in the systemsettings -> multimedia settings.

In spanish is: system settings -> Audio and Video
In this settings, I try all configs with same result.

When using Audacity it won't use pulseaudio most probably but stick to alsa. This needs perhaps seperate configuration via alsamixer -c 1 in the terminal.

In Audacity, only I have Alsa, not pulseaudio

For me, this its important because I work a lot of with audio.

Regards!
