hello,<br>
<br>
i need help to understand a major problem i had today.<br>
<br>
i'm unsing a old computer for a project, running ubuntu linux 10.04, with a presonus FP10 fire wire soundcard with jack.<br>
everything was running fine for weeks when we worked on this project.<br>
i boot this computer 3 days ago, start pd and everything was working wey well for all rehearsal.<br>
(i did not close pd since)<br>
<br>
<br>
the problem i've experience is that pd freeze during the performance.<br>
<br>
<br>
(fortunately, it was 10 000 Km away from where i'm living so i have no friend on the audience)<br>
This is my 1st unexpected pd freeze (when i'm not on edit mode) since i begin using pd, 11 years ago.<br>
i'm running pd vanilla with almost no externals<br>
thanks to Murphy's law, it occur in performance, and not in rehearsal.<br>
<br>
worst of all : i don't know what is the problem, and can't make things work again.<br>
<br>
So, the 1st thing i could imagine is a hardware problem, since the software was tested for month.<br>
(This patch work for weeks without closing pd, and this pd installation run for 8 month for an installation).<br>
<br>
fact are :<br>
- after rebooting the computer/soundcard etc, jack start and works<br>
- audacity can connect to jack.<br>
- pd crash on start-up if started with jack.<br>
- i do not change anything about pd<br>
- i did not physically touch the computer for the last 10 minutes before the freeze (everything is automatized)<br>
- this computer is not connected to internet, i did not do any update since it was stable.<br>
- the soundcard works OK on an other computer on osX.<br>
<br>
i'll use another computer for tomorrow performance, and i'll have more time to understand the problem when i'll be back home, however i would really appreciate to understand as soon as possible what could cause a huge problem like what i experience today.<br>
<br>
So, with that mail i share my shame with you, but i also really apreciate to have some pointer about what to test in order to understand the problem.<br>
Why pd can't connect to jack anymore, since jack work and noting was change about pd?<br>
and why this occure during a live performance...<br>
<br>
<br>
thanks for your consideration,<br>
<br>
cheers<br>
Cyrille (sad)<br>
