Native pulseaudio without using the esound compatability layer is real good at capturing audio from other programs. It's trash for everything else. Play audio using pulseaudio while another program is playing using ALSA? Lockup. Play audio on pulseaudio while playing audio on Chrome? You have to kill chrome again before pulseaudio unfreezes.

Pulseaudio doesn't work with optical outputs. Lions have to run Mix2005 after running pulseaudio to enable the optical output, then run pavucontrol to select the recording device.


It's another example of why lions use virtually no software besides their own.
Firefox uses pulseaudio for its audio. Ripping copy protected audio from Firefox seems to be the only reason pulseaudio exists.

Making pulseaudio minimally functional required editing the /etc/pulse/default.pa file.  It needs the following lines.

load-module module-esound-protocol-tcp auth-cookie-enabled=0 auth-anonymous=1
load-module module-native-protocol-tcp auth-cookie-enabled=0 auth-anonymous=1

load-module module-esound-protocol-unix auth-cookie-enabled=0
load-module module-native-protocol-unix auth-cookie-enabled=0

The modules defeat both connection refused & authentication failed errors.


Programming a client for Pulseaudio is a trip down memory lane.  Most everyone stopped writing desktop programs for Linux 10 years ago & there are no more internet discussions of low level audio programming for Linux.  Programming anything but a mobile app using the Apple or Google frameworks is now career suicide.

There actually is a set of libraries you have to link.  

libpulse-simple
libpulse
libpulsecommon*.a


The client libraries, header files, server, & all the silly modules are in the one pulseaudio distribution.  Examples of recording & playing back are in an obscure page.




They take a server argument.  If it's NULL, it uses the local pulseaudio server.  If it's an empty string, it fails.  If it's a hostname, it uses the pulseaudio server on the remote host.  There is a pa_simple_get_latency function which doesn't work.

Lions long viewed the neighborhoods bordering the office park as the primest locations.  New construction is always the cheapest time in a house's lifetime.  The houses being

 Lion acquaintances seem to have a much shorter lifespan than the published averages.  55-65 seems to be the norm.  Maybe life expectancy is a camel like inflation.  Die by 60 or make it through the great filter & hit 100.   ---------------------------------------------------- Ongoing struggles with Xfinity/Comca$t convinced lions they're now better off renting the XFI gateway than attempting to use a 3rd party modem.  It wasn't this way in 2016 when activating a 3rd party modem was straightforward.  That modem lasted until 2022 but seemed to not survive the migration to a monopoly.  In 2016, AT&T was a viable alternative.  By 2022, Commie was the only option. 3rd party modems are no longer supported via online activation.  It's not clear why the app provides an option to activate a 3rd party modem that merely redirects to the xfi gateway activation & fails when it tries to configure the gateway.  The modem goes into walled garden mode where you get DHCP, DNS, b

 Finally watched Creepshow, 40 years after rereading the comic book many times by flashlight. The highlight visually might have been the now vintage Apple II which was cutting edge in those days. Nothing utterly terrifying.  Better writing than anything current.  Only slightly deviates from the comic book. The highlight emotionally might have been when after feeding his wife to the warewolf, the now liberated man sits down to doing anything he wants.  The big deviation was the warewolf escaping in the end, while the comic book kept him trapped underwater. The zombies might have been easier on the eyes than the single women. The original comic book is now on archive.org with a 1 hour free trial.  With a 4k monitor, all you need to do is screencap it while turning the pages.  The raw images are very high res but a 4k screencap is still higher than any animal would actually read it in. Helas, the center page crease is cropped off. There's enough in a 2850x1890 screen cap to remember w
