Re: [PD-dev] Tentative fix for the -nogui no-sound problem
As I understand it, the zero sample rate happens simply because the variables that are queried by plugins (specifically sys_dacsr) are initialised after the plugins are loaded. Loading the GUI forces the audio settings to be initialised earlier so the problem doesn't happen under 'normal' conditions.

Re: [PD-dev] Tentative fix for the -nogui no-sound problem
That could be the solution, I haven't looked enough to know yet. My question is: what is causing the sample rate to first be sent as "0"? I remember that seemed to be one of the behaviors related to this. Its probably something we want to prevent from happening, unless someone can explain why Pd announcing the sample rate as 0 is useful. .hc On Apr 13, 2012, at 9:44 AM, Chrissie Caulfield wrote: > Hiya, > > I've been looking into the problem that starting pd with -nogui can cause a > lot of plugins to start with a zero sample-rate and therefore produce no > sound. > > Here's my tentative patch for this.

[PD-dev] Tentative fix for the -nogui no-sound problem
Hiya, I've been looking into the problem that starting pd with -nogui can cause a lot of plugins to start with a zero sample-rate and therefore produce no sound. Here's my tentative patch for this. It's very small and though it could be regarded as over-simplistic, it does fix the problem that's been causing me a lot of grief for a while now. So, I tentatively offer this as my fix. If you think it's not enough and needs something more complex then please say what you think is wrong and I'll keep digging :) Chrissie diff --git a/src/s_audio.c b/src/s_audio.c index 8434f52..7cff1c8 100644 --- a/src/s_audio.c +++ b/src/s_audio.c @@ -328,6 +328,7 @@ void sys_set_audio_settings(int naudioindev, int *audioindev, int nchindev, sys_log_error(ERR_NOTHING); audio_nextinchans = inchans; audio_nextoutchans = outchans; +sys_setchsr(audio_nextinchans, audio_nextoutchans, rate); sys_save_audio_params(nrealindev, realindev, realinchans, nrealoutdev, realoutdev, realoutchans, rate, advance, callback, blocksize); ___ Pd-dev mailing list Pd-dev@iem.at http://lists.puredata.info/listinfo/pd-dev
