Audio output default sink not on index 0 card/port.

[FGrose]

Observed in Fedora-SoaS-Live-x86_64-32-1.6.iso installed as LiveUSB image on physical hardware.

For example the Speak Activity is silent.

See comments below.

A defect because the 0 index device is conventionally made default (although there may be more to the convention).

Engineering an appropriately simple control, for changing the default might be considered.

Testing on physical hardware, booting the Fedora-SoaS-Live-x86_64-32-1.6.iso directly using this grub menuentry:

menuentry 'SoaS 32 Live' --class fedora --class gnu-linux --class gnu --class os {
    insmod part_gpt
    insmod ext2
    set root='hd1,gpt2'
    set isolabel=Fedora-SoaS-Live-32-1-6
    set isofile=/Fedora/Fedora-SoaS-Live-x86_64-32-1.6.iso
    loopback loop ($root)/$isofile
    linux (loop)/isolinux/vmlinuz boot=isolinux iso-scan/filename=$isofile root=live:LABEL=$isolabel ro rd.live.image rd.live.ram
    initrd (loop)/isolinux/initrd.img
}

The Speak Activity and Clock Activity are silent.

Problem is confirmed on a different computer, monitor, & video/sound card. Actually, Fedora Workstation also defaults to card/port index 1.

The default sink is configured at the wrong port.

Using the PulseAudio command,

$ pacmd set-default-sink 0

gave voice to Speak and made Sugar sound again.
