i cant cotnrol the loudness of audio in pd-extended, it doesnt make any difference if i run pd while JACK running or with ALSA! Im using ubuntu 14.04, any ideas would be highly appreciated!
No control on Pd-extended's loudness!
What exactly you mean you can't control the loudness of audio in Pd? Pd doesn't have a volume slider built in, but you can either use the system volume to control it (relative change), or you can multiply the signal by a value smaller than 1 before the [dac~] (absolute change).
i mean controlling the system Volume (not from inside the patch). If pd is running the system volume gets out of function, so i cant turn the volume of the speakers lower or higher.
Your system volume is probably Pulse audio. which is disabled by Pd. Install alsamixer (alsa-utils).
