Re: [gentoo-user] Poor mans audio in the world of the great Jack D.
Staring into the dark abyss of the fathomless mysteries, the humble scholar spake: Shit! I'm out of ideas, dude… The .asoundrc snippet works out of the box for me, but I use it just for Firefox, to be honest, every other audio software There are more solutions at http://jackaudio.org/faq/routing_alsa.html Failing that, I don't know. Maybe qsstv does not belong to the ALSA tribe but to the OSS one, and uses the ALSA OSS emulation, and this prevents the ALSA jack plugin to work? -- Emanuele Rusconi

It seem so, that no cunning foe is stealing the resource, for the
great Jack D.'s voice to be heard.
So the humble scholar found another word of hope, buried deep within
the arcane tomes:
for the .asoundrc spell, for the rite to be complete
that will allow the foreigners to be heard by Jack D.,
the caster needs an artifact, a mystic scroll from the Great Library,
and that scroll is named /usr/lib/alsa-lib/libasound_module_pcm_jack.so
and can be summoned with the magic words:
# sudo USE=jack emerge -av media-plugins/alsa-plugins
-- Emanuele Rusconi
:)
And Gentoo folks they are and followed their prophet Emanuele in doing
so and finally found what he was telling them to be found in the great
system.
And the great system shouted out:
[I] media-plugins/alsa-plugins
Available versions: 1.0.27-r1 ~1.0.27-r3 1.0.28 ~1.0.29 {debug ffmpeg
jack libsamplerate pulseaudio speex ABI_MIPS=n32 n64 o32 ABI_PPC=32 64
ABI_S390=32 64 ABI_X86=32 64 x32}
Installed versions: 1.0.28(19:27:03 04/16/15)(ffmpeg jack libsamplerate
speex -debug -pulseaudio ABI_MIPS=-n32 -n64 -o32 ABI_PPC=-32 -64
ABI_S390=-32 -64 ABI_X86=64 -32 -x32)
Homepage:http://www.alsa-project.org/
Description: ALSA extra plugins
#locate libasound_module_pcm_jack.so
/usr/lib64/alsa-lib/libasound_module_pcm_jack.so
/usr/lib64/debug/usr/lib64/alsa-lib/libasound_module_pcm_jack.so.debug
But still the great Jack D. keeps its mouth shut and forbid to talk
with alsa tongues.
So the Gentoo folks asked themselves: Does the great system knows
about the alsa-plugins being part of it? Or does the great systems
need even more things to be told?

Perhaps the great Jack D. Is talking to itself?
The pcm.!default line says: when opening alsa, connect to rawjack
The earlier .asoundrc says: when opening alsa rawjack, direct the
connection to the great Jack D.
If the jackd connects to the default alsa output, aka rawjack, coult it be
tripping itself up? Is there maybe a jack option to direct the alsa output
to the sound hardware instead?
Looks like I'm off on the wrong track... by default, jack connects to the
hw:0 alsa device, which is the sound hardware.
This page has another example of asoundrc config which might work better
for you.
https://wiki.archlinux.org/index.php/JACK_Audio_Connection_Kit
(search for Playing nice with ALSA)
The config file contents is:
# convert alsa API over jack API
# use it with
# % aplay foo.wav
# use this as default
pcm.!default {
type plug
slave { pcm jack }
}
ctl.mixer0 {
