pavucontrol

#1 Post by sheepy »

If anyone could bring any version of pavucontrol to puppy, you would be my hero.
Pavucontrol is a pulse audio mixer. It came with the earlier versions of Ubuntu. The cool thing about it is that you can make audio coming out of your speakers go through your microphone. Great for recording audio out of your speakers or screensharing videos in a video chat.

Hi, sheepy.

You say:
> The cool thing about it is that you can make audio coming out of your speakers go through your microphone.

Huh, not cool, if I remember my acoustics class well. That creates a sound loop and... an ugly and loud screech in the audience!

Sorry to burst your bubble... :(

BFN.

Hmm, it works fine on any debian-based distro I've used so far. If you use it to change the analog stereo duplex to output, then whatever you hear through your speakers will act as the input for the microphone too. I did it last night in Ubuntu during a video chat and it worked great. The quality is identical.

<ot more-or-less>

Long ago..

'microphones' could be hooked up as an (inefficient) speaker. Why the earliest telephones had a post-mounted mic and the speaker on a cord that was held to your ear. Ever watch an old movie where someone on a phone flipped the two? It happened sometimes ;)

I'm guessing there's some sort of mixdown for ambient sound in your soundcard s/w so the dreaded feedback loop isn't happening. I'd imagine most consumer mics have a high dropoff in the polar gain pattern as well. Modern tech :lol:

It basically turns off your microphone, but routes your speaker output to also go to your microphone input, so they are perfectly identical. You can route all sorts of audio wherever you want. Pretty neat stuff. I wish there was a simple way it could be done in Puppy. :\
I spent all day trying to bring pavucontrol to Lucid and have had no success. D:

Turns out it can be done with ALSA on Puppy, using the Line-In mic jack mode. However, it creates a lot of white noise, whereas pulseaudio does not.

So, tell us how you got it work with alsa, please. Maybe it can be improved on.

pulseaudio

#8 Post by stifiling »

I've gotten it working on Lucid, Slacko, Nop 431, and Saluki.

1 addgroup pulse
2 addgroup pulse-access
3 adduser pulse -G pulse (just press enter twice, no password}
4 cp /etc/group /etc/group.bak
5 manually edit the /etc/group file and manully add the users pulse and root to the following groups to look similar to:
root:x:0:pulse
audio::101:root,spot,fido,pulse
pulse:x:1001:pulse,root
pulse-access:x:1002:pulse,root
6 install the attatched pet
7 reboot the machine
8 run the command: pulseaudio --system
9 go to the menu and run PulseAudio Volume Control

Here it is on SalukiNOP

pulseaudio --system command error

#9 Post by michaellowe »

hi stifiling, I followed your instructions:

I've gotten it working on Lucid, Slacko, Nop 431, and Saluki.

1 addgroup pulse
2 addgroup pulse-access
3 adduser pulse -G pulse (just press enter twice, no password}
4 cp /etc/group /etc/group.bak
5 manually edit the /etc/group file and manully add the users pulse and root to the following groups to look similar to:
root:x:0:pulse
audio::101:root,spot,fido,pulse
pulse:x:1001:pulse,root
pulse-access:x:1002:pulse,root
6 install the attatched pet
7 reboot the machine
8 run the command: pulseaudio --system
9 go to the menu and run PulseAudio Volume Control

Link:
pulseaudio.pet
when I ran the command pulseaudio --system I got the error message returned saying: pulseaudio: error while loading shared libraries: libspeexdsp.so.1: cannot open shared object file: no such file or directory

and here is what my group file in /etc looks like

root:x:0:pulse
daemon:x:1:
tty:x:2:
ppp:x:200:
users:x:500:
nobody:x:65534:
guest:x:501:
spot:x:502:spot
bin::2:root,bin,daemon
audio::17:root,spot,fido,pulse
503:x:503:messagebus
ftp:x:1000:
dip:x:30:
uucp::10:
lpadmin::112:root,spot,nobody,guest
netdev::113:
haldaemon::119:
sshd::33:sshd
webgroup:x:504:
pulse:x:1001:pulse,root
pulse-access:x:1002:pulse,root

Any ideas what is going on, I have had this sort of error message before in the console what does it all mean?
cheers :?

Not sure why that lib is missing....it's included in my lupu_525...saluki also. nonetheless....i attached them. so you can untar the file...and drop them in the /usr/lib directory. Let me know if it works.
