Flash does not like pulseaudio
I get no sound from flash with pulse audio, it does not detect it, and I put the asoundrc in /etc and still no luck.
Youtube videos won't play at all and other sites play with no sound, pulse works with everything else though.
I need to use it to record internal audio and using the alsa loopback yeilds the same result.
Any suggestions? I use Slackware 14.1
asoundrc
Code:
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
pcm.!default {
type pulse
}
ctl.!default {
type pulse
}

Hi Gumboherpy,
pulseaudio is not supported in flash.
the following configuration file could solve the problem.
/etc/asound.conf
Code:
# Use PulseAudio by default
pcm.!default {
type pulse
fallback "sysdefault"
hint {
show on
description "Default ALSA Output (currently PulseAudio Sound Server)"
}
}
ctl.!default {
type pulse
fallback "sysdefault"
}
# vim:set ft=alsaconf:

Unfortunately Flash was geared more with ALSA's dmix and OSS's ossmix in mind rather that pulseaudio. You'll have to use them if you want Flash audio media.

The above input did not help things at all, videos in youtube play now but still no sound. I am willing to ditch pulseaudio but I need somehow to record internal computer audio. (for gameplay recordings and such) I tried setting up an alsa loopback and that yeilded no results, same thing. Anyway you guys know on how to record computer audio? Thanks.

JACK and ESounD work with ALSA directly via routing audio streams rather than against it trying to force it across an API layer. You might have better results with those. As Eric said in that blog, ESounD does take some work, but it works rather well. JACK is just dynamite however.
http://slackbuilds.org/repository/14.1/audio/jack2/
JACK2 is the more modernized version. And the JACK homepage has plenty or articles to set it up.

Okay so I tried following Alienbob's tutorial and everytime I try to run the alsa2jack loopback I get this error via terminal.
Code:
herpy ~

And this is what my jackdrc looks like
Code:

What am I missing? |

In Debian with MATE 1.6 and MATE 1.8 I have no problems at all with Flash and PulseAudio working together. Do you have other systems you can use to confirm the problem or do you just use Slackware?

It would be nice if people can get away from the "personality" thing. I actually do like PulseAudio, it "just-works" on my laptop when ALSA doesn't. Instead of bashing something because of the person behind it it would be great if you could actually offer help. |

It works on debian so it is a slackware issue. My soundcard is hw:0'0. Thats what I'm trying to record sound from.

What browser are you using? Flash and Linux are slowly separating. Flash is up to version 13 while it is stuck at 11.2 in Linux so some flash sites won't work properly or at all in Firefox/Iceweasel and you will be forced to use Chrome (or Chromium with pepperflash extracted from Chrome) to actually use flash sites.
The other thing you can do is force YouTube to use HTML5 rather than flash or use a Firefox extension that converts Flash to a range of other video types that you can use.

Not Dumb, I had to look for it a while back. Go to this page and select HTML5 at the bottom. If you are signed in it will remember the setting, I'm not sure if it will remember it if you're not signed in. |
