Subject: A few Machines crash when "no default audio driver available"
Date: Thu, 09 Jul 2026 13:44:19 +0200 [thread overview]
Message-ID: <87o6gge6b0.fsf@pond.sub.org> (raw)
I stumbled over ARM machine musicpal, PPC machines pegasos1, pegasos2,
and MIPS machine fuloong2e crashes.
I run them like this:
$ qemu-system-aarch64 -M musicpal -nodefaults -S -display none -monitor stdio

Died when device_set_realized() tried to propagate a "no default audio
driver available" error to &error_abort.
The error comes from audio_init(). Backtrace:
