hence the note:

and no longer relevant in mythtv 0.23 and later. "

0.24 fully supports pulse audio natively.
Any previous version of myth would have worked with ALSA:pulse device,
provided you started myth with a special parameter that wouldn't
disable pulse.

My guess is that you have carried on the settings from an earlier install.

if using 0.24 ; go into the audio settings page and scan for audio
device , then select in the list of audio devices the one you want.

if you want to use digital audio, your device name will contain either
iec958 or hdmi depending on your audio card.

if you want to use pulse, select either ALSA:pulse (recommended) or

If using trunk, no need to scan for audio devices, the list is always
up to date as you enter the settings page.

ALSA:default was the default device myth automatically configured a
long time ago ; set up the audio output device to the actual device
