Re: [pulseaudio-discuss] Running under Windows 7

It's erroring out loading waveout saying it can't load wavein. I can post the exact error if required. Since the win32 binaries are quite old, I am wondering if there is anything more recent out there. How does one compile PA under Windows. I do have Cygwin installed but understand PA doesn't use that. PA once built on Windows, but that was (as you say) a fairly old version released by Cendio. Since that time, changes have been committed that are incompatible with mingw and/or Cygwin, but the changes are nonetheless beneficial to PA's feature set and performance on Linux/OSX/UNIX. PA will need to be re-ported to Windows to build a more recent version of PA on Windows. However, rather than porting an old version, I think it makes sense to port the current git master, and keep updating it whenever someone commits a patch that does not properly deal with Windows toolchain and/or library discrepancies. There have been quite some volunteers I've observed on the ML volunteering to contribute patches to fix PA on Windows, but I don't know of the degree to which they've been successful. On the other hand, Cygwin 1.7 is said to improve on its compatibility with existing Linux-targeted sources, so it may be worth it to re-examine that option. I might not be up to date on the latest developments, but I think it's safe to say that current PA git master is unlikely to compile on Windows under any toolchain. Finally isn't wavein just for recording. Since I don't need to record, is there a way to just skip that module? module-waveout, as documented here http://pulseaudio.org/wiki/Modules#module-waveout appears to have a parameter called record which, when set to 0, does not try to initialize wavein. Make the following change in default.pa (or system.pa): load-module module-waveout record=0 name=blah Best, Shane ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss Sean ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

OK, this now coming from an upgraded to F11 box... However no sound working as yet so it's been one step forward, two steps back... Did you check all the output levels are unmuted for your card? Try running alsamixer from the commandline. Cheers.

Output was being sent to the sound device on my Radeon graphics card (which I assume comes out the HDMI connector ?) Anyway all going now. So, what are the steps to upgrade my pulseaudio to the latest version ? I assume I can't just remove the pulseaudio rpm as that will break dependencies ?

[pulseaudio-discuss] passthrough audio (eg. AC3 / DTS / WM9)
Hi Everyone. I'm really sorry if this has been covered before, I've read back through the past 6 months list history and found nothing and my OS (ubuntu) and application support forums/lists are not being very helpful. I would like to pass digital audio completely unaltered (bit-stream) to my SPDIF output - Can this be done with pulseaudio? (Yes, I understand that I will lose sound mixing and the ability to have multiple application use the sound device) For example: If I have a stereo PCM file @ 16bit / 44.1khz - Then output at this type (do not resample in any way) ... or PCM @ 24bit / 96khz etc. If I have AC3 / DTS @ 48khz - The output this original data exactly. (I am using an external decoder/processor and do not want the original audio data changed in any way). Again - sorry if this is a stupid question, or already answered. I could not find a definitive answer I would like to keep pulseaudio if possible - as it is what my Linux distro (ubuntu) has set default. Thanks in advance. ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss
