hei PD-people,

i do have problems with the sound output in pd. i'm using ubuntu 12.04 and pd 0.43.4 .
it did cost me a lot of time installung the programm cause of ubuntu 12.04 - finally i did it, but have no output sound, when i test it with an own patch or the "Media->test audio..."-testing-patch.
when i click on media->preferences->audio settings... i cant choose neither an input nor an output device. when i start puredata in the terminal with: "pd -listdev" i get the text file in the pd-Main-window:

"
no audio input devices found
no audio output devices found
API number 2

no midi input devices found
no midi output devices found
"

i tried enter the pd path in "media->preferences->path", so the prog searches after libraries or something for the audio devs...dunno....helped nothing

in an older pd version i set the audio preferences to ALSA and i got sound. but this choice i dont have in this version, neither works in terminal: "pd -alsa".

i do have sound in all other programs (if sb thinks its a general sound card problem..).

unfortunately i dont have any informations to my sound card. its an old acer laptop (1694WLMi). not originally mine....

i dont find any help in the internet for this case. not in this forum, too.
any help would be very nice!!

thank you in advance!!

ok. i'll work through the troubleshooting....& write what happened. thanks.

i've not installed jack_control....should i?
through alsamixer i got following information:
soundcard:
0 [ICH6]: ICH4 - Intel ICH6
Intel ICH6 with Cx20468-31 at irq 17
driver:
Advanced Linux Sound Architecture Driver Version 1.0.24

..but nothing else (unusual).
hmm - maybe i should try installing pd again..

unfortunately there are no sound card options in my BIOS.....:(

i'm also very new in Pure Data......
your patch has shown me, what's possible with PD. that's exactly i wanna do with it.
thanks for the motivation. nice work.
