Yep, when a software demands alsa (like pd does) it gets stuck. Jack is the way to go, but it actually works the same way, 'cause once jack gets a hold of alsa, everything else that is not communcating to jack and is demanding alsa will also be stuck. The trick is making/using programs that can talk to jack (i.e.: my audio player is mocp, video player is vlc, daw is ardour, etc... etc... they all can use jack as output).
Making flash plugin / browser going to jack has been coverd in many forums. example: - http://ubuntuforums.org/showthread.php?t=843012 note: Last time I tried to put my chrome+flash_plugin working with jack it took a bit of long time and a lot of ubuntu studio forum reading! best of luck, Pedro On Mon, Dec 6, 2010 at 8:21 AM, IOhannes m zmoelnig <[email protected]> wrote: > On 2010-12-05 22:34, Aaron L. wrote: > > This is somewhat of a complete newb issue so I apologize up front for > > that....... > > > > However, it seems that I cannot use pdextended and watch a youtube video > at > > the same time (the youtube vid is a pd tutorial). > > > > Here's what it's starting with: > > > > pasuspender -- /usr/bin/pdextended -alsa %F > > > > Is it absolutely necessary to start pd with 'pasuspender'? > > > > When I don't (i.e. start it like this: '/usr/bin/pdextended -alsa' ), I > get > > a bunch of 'device or resource busy' messages in the terminal and I don't > > get any audio when doing the whold testtone thing). > > > > Is there any way around this? > > > well, this is exactly the way how alsa is supposed to work: > - only one application can access a (hardware) device at any point > > pulseaudio is a way to circumvent this limitation. > running Pd in pasuspender, effectively disables pulseaudio including all > it's features. > > > luckily there are ways around that. > > - use pulseaudio (not a good option, as Pd currently doesn't support it > :-(; btw, pa is geared towards the ordinary consumer multimedia desktop > where people would like to watch their youtube videos and at the same > time listen to the latest p!nk smash hit; Pd is not really targeted > towards that marketm, hence pa is not done yet) > > - use alsa's "dmix" interface; "dmix" is a virtual device that allows > several applications to send their audio output to the same hardware > device (without the applications even knowing of it). i'm not 100% sure > whether you can actually access this from within Pd.... > > - use "jack". now you can think of jack as "pulseaudio for pros", it > allows to route the output of one process to the input of another > process (or more); "process" can be both hardware (your soundcard) or > software (Pd, your browser,...). > there are also ways to make alsa-only applications (e.g. your browser) > use a pseudo alsa device that really sends all audio to jack (thus the > application need not be aware of jack at all) > > > madt > IOhannes > > > _______________________________________________ > [email protected] mailing list > UNSUBSCRIBE and account-management -> > http://lists.puredata.info/listinfo/pd-list > > -- Pedro Lopes (MSc) contact: [email protected] website: http://web.ist.utl.pt/Pedro.Lopes
