Re: [PD] That old -nogui/nosound problem on Linux ...
Just for info, here's the little patch I'm using at the moment. Contrary to what I said in my last email it doesn't actually need -r rate to make it work, it fixes all uses of -nogui that I have tried :-) Chrissie diff --git a/src/s_main.c b/src/s_main.c index 87e13c8..b95d2c3 100644 --- a/src/s_main.c +++ b/src/s_main.c @@ -1038,6 +1038,7 @@ static void sys_afterargparse(void) callback = sys_main_callback; if (sys_main_blocksize) blocksize = sys_main_blocksize; +sys_dacsr = rate; // CC Hack to fix startup rate sys_set_audio_settings(naudioindev, audioindev, nchindev, chindev, naudiooutdev, audiooutdev, nchoutdev, choutdev, rate, advance, callback, blocksize); ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] That old -nogui/nosound problem on Linux ...
I have had a similar problem when upgrading from Hardy to Lucid / Natty. In my case it was [susloop] that didn't work anymore with the -nogui flag. I wrote an abstraction to do the same thing and my patch was working again. It looks like some objects need updates to work with a newer OS and -nogui.

So, does anyone have any (even vague) ideas of where to start before I start randomly digging? Vague guess, might be wrong: I think the bug is that pd -nogui loads (and possibly also loadbangs) the patches specified on the commandline before it initialises the samplerate~ and block~ settings. polygate~ (or other broken dsp externals) are probably getting the samplerate~ or block~ settings before pd has fully initialised them. (eg: object gets samplerate in the object's 'new' method) hip~ and friends work with various workarounds probably because they re-get the samplerate~ or block~ settings when the dsp graph is resorted. (eg: object gets samplerate in the object's 'dsp' method) polygate~ (or other broken dsp externals) are possibly not re-getting the samplerate~ or block~ settings when the dsp graph is resorted. This suggests a possible other workaround that combines two techniques: loader.pd: [loadbang] | [delay 10] delay a bit because Pd has a bug | \ | [; pd dsp 1(turn on dsp to initialize things | [delay 10] | \ | [; pd dsp 0(turn off dsp in case it slows down loading | [delay 10] | [; pd open main.pd .( load the main patch (syntax not tested...) main.pd: your normal patch, feel free to [loadbang]--[; pd dsp 1] as usual, if it doesn't work after all that fuss then I'm out of ideas. Of course, even if the combo workaround works, it's still just a hack and pd still has a real bug that needs fixing, and the externals in question might have real bugs that need fixing too. But it'd provide a further clue. Claude ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Hey Chrissie, That would be awesome if you fixed it! Its been discussed before, perhaps on pd-dev. I think matju once outlined what the cause was, but I can't remember specifics. .hc On Apr 10, 2012, at 11:11 AM, Chrissie Caulfield wrote: Hi all, I've been scouring the lists for a solution to this but none of them seem to work for me.
