Problems with `pactl load-module module-loopback'
Hi all. Without pipewire I didn't manage to pair and connect my bluetooth headset/microphone to my Debian 12 so I installed pipewire while pulseaudio was already there. So now both pulseaudio and pipewire are installed. Now when I do: $ pactl load-module module-loopback latency_msec=5 a terrible noise suddenly comes, and if I want to stop it with $ pactl exit I get the error message `exit failure: connection refused'. I searched around but didn't find so far any solution. Please help whoever can. Thanks in advance, Rodolfo
Problems with `pactl' after replacing pulseaudio with pipewire
In order to have my headset bluetooth microphone detected by Debian 12 I removed pulseaudio and in its place installed pipewire. Only, since then, when I do $ pactl load-module module-loopback latency_msec=5 a terrible continuous noise comes up, and besides when I do $ pactl exit I get the error message `exit failure: connection refused'. I searched around but didn't find so far any solution. Please help whoever can. Thanks in advance, Rodolfo

Following your example, I aptitude-installed acpid and created /etc/apt/events/briteup and /etc/acpi/actions/brite and filled them with the stuff you reported; and then I did `chmod +x brite'...

The problem seems to be solved after I removed the file /etc/resolv.conf, that included a certain nameserver... Thanks, Rodolfo
Temporary failure in name resolution
Debian 12 on Thinkpad T450s. The error message `Temporary failure in name resolution' appears whenever I log into X with `startx' at prompt after boot, but it *only* occurs if the PC is *not* connected to internet; otherwise it does not appear; nevertheless, it annoys me and I wish to get rid of it.

Thanks, sorry: the printer is the Samsung ML-191x 252x Series, the software I'm using to manage it is the Debian package cups and `aptitude show' says it's installed in my Sid box at the version 2.4.2-1+b2.

Thanks. 4 years ago I started the present conversation ("Live recording") and
listers suggested me to get an audio interface. Now I bought one and resumed
the conversation. For the particular problem of "multichannel playback" some
listers here suggested me to apply linux.audio.users mailing list.

Thanks, David. What is specifically your audio set, much simpler as you say?

[solved!!!] Multichannel audio playback

It works...!!! That's what I did: 1) I plugged the Behringer into the mains; 2) I connected the Behringer to the PC via Behringer's USB cable; 3) I plugged 3 amplified loudspeaker (could also be not amplified but then sound is low) into 3 of the 4 black holes (the TRS ones, but it could be ok also with the RCA ones, I didn't try yet) of the `PLAYBACK OUTPUTS' system on the back of the Behringer; 4) from my Linux box I did: $ ecasound -f:16,3,44100 -i:sndfile,3canali.wav -o alsaplugin,2,0 where `3canali.wav' is a 3-channels file. And voilà: each of the 3 loudspeakers play a different channel of the 3 channels composing `3canali.wav'. There don't seem to be any issue with Behringer's controls: the `MAIN OUT' and `MIX' knobs can be whatever, such as the `STEREO/MONO' switch (so it seems). Thanks to each and all that helped...! Cheers Rodolfo

Capture screen with mencoder
I posted this to Mplayer mailing list but got no answer so am sharing it here hoping someone can help...

No, certainly, my fault... I just did:

Your guess seems to be true:
# aptitude purge liblilv-0-0:i386
The following packages will be REMOVED:
liblilv-0-0:i386{p} libserd-0-0:i386{u} libsord-0-0:i386{u}
libsratom-0-0:i386{u}

Do you want to continue? [Y/n/?]
, so it's also important that appendix `:i386'. Now, I want to remove all tha
packages I installed on last july 23th. To do so, I do:
$ grep "2015-12-19.*.install " /var/log/dpkg.log | awk '{ print $4 }' | cut
-d: -f1 | tr '\n' ' '
How can I modify the above command so to include - when it is present - also
that important suffix?

Clear now, thanks...
Now, when I try to remove liblilv-0-0, Debian warns me that audacity depends on
it:
# aptitude purge liblilv-0-0
The following packages will be REMOVED:
liblilv-0-0{p}
0 packages upgraded, 0 newly installed, 1 to remove and 192 not upgraded.
Need to get 0 B of archives. After unpacking 132 kB will be freed.
The following packages have unmet dependencies:
audacity : Depends: liblilv-0-0 (>= 0.16.0~dfsg0) but it is not going to be
installed
But audacity is installed on my Debian box since months... How can it depend
on a package installed a few days ago...?

Thanks to you all. Then, e.g., 2020-07-23 08:02:37 install liblilv-0-0:i386 0.24.2~dfsg0-2 means that liblilv-0-0 has been installed or not on 2020-07-23? From dpkg manpage, --log option, as I understand, the field with `' should correspond to the installed version, so `' seems to state that it is not installed at all...? If so, what does the `install' action do there...? thanks again, rodolfo

Mencoder and ffmpeg
Hi all. I wanted to capture my webcam streaming and audio using ffmpeg but banged against `a sea of troubles': sync problems, video freezing, video stuttering, background noise, choose of one format rather than other... Mencoder instead at once easily, with: $ mencoder tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0:forceaudio:alsa:adevice=hw.1,0 -ovc lavc -oac mp3lame -lameopts cbr:br=64:mode=3 -o webcam.avi did perfectly the job. But Mencoder is hardly ever used compared with ffmpeg... I wonder why so much difference in this case between the two respective behaviours and wish to know what you listers think about all that... thanks for any help cheers rodolfo

updmap-user: command not found
Hi all. On my Debian Stretch box, the `updmap-user' command is declared `not found' although the package texlive-base is installed. Why? Please help. Thanks in advance, Rodolfo

How to have password shown?
Hi all... Is there any a way to have my user-password shown when logging into Debian in tty console, or also within X system when changing to root? It is for my old father... it'd be easier for him to see what he's typing. In internet I found some procedures to have asterisks shown; would it be possible to have a clear text as well? Maybe it isn't as I understand... Thanks for any help, Cheers, Rodolfo

My case was, I think, the one described: even canceled the jobs from PC, the printer was continuing printing and only turning it off could stop it... After turning it on again, it started printing again but only a few more pages, then stopped definitely. Before turning it off, I had also deleted the printer from CUPS managing centre, but this was maybe not important. Rodolfo

To satisfy dependencies, you'll need to downgrade libsystemd0 as well (and libpam-systemd, libnss-systemd, systemd-* in case you have those installed) it's a quite delicate issue... After all, since I can shut off PC with external button, I can survive with the problem until fixed... rather than facing such a delicate matter (so it seems to me to be). Rodolfo

Keyboard not responding after exiting X
Hi all. In order to have PDFtoMusic properly installed and work (see thread `PDFtoMusic installation') I had to do a full-upgrade to unstable. Everything is ok now except that, when logging out X (graphical environment, window manager), the keyboard is totally not responding so that I have to power off using the external button on the computer case. Anyone experimenting the same problem? Please help whoever can. Thanks, Rodolfo
