For Mick's .wav files, I would use mpv to play them, which gives an
elapsed time indication, and sox to extract the desired section.
(Sound-wise, I'm ALSA-only.)

If you don't require too much precision, mpv is a quick wav of
finding, say, the gaps between tracks when you dub a vinyl record,
using Left/RightArrows, SpaceBar, and l to loop a section.

$ sox infile.wav outfile.wav trim  
will extract a section. If I need precision, or want to impose
a fade or other effect, I use soxy to "rehearse" the sound, eg
$ soxy infile.wav trim 6:18.8 10 fade h 0 -0 4
would play just the last ten seconds of a recording of length
6:28.8, with a four second face-out.

$ type soxy
soxy is a function
soxy () 
{ 
[ -z "$1" ] && printf '%s\n' "Usage:${FUNCNAME[0]} 
path-to/sound-file-of-any-type [trim 20 2]
runs sox to play the file with any arguments given.
The example above reminds you to put the full argument." 1>&2 && return 
1;
local From="$1";
shift;
sox -q "$From" -t alsa default "$@"
}
$ 

For generating multiple tracks for burning to a CD, I've always used
my own Python programs for over twenty years. They take account of
the divisibility of Nsamples by 2352/4 when the WAV format is CD-type,
and chunk the data to prevent overloading CPU/memory. (I was using a
Pentium II (Klamath) @266MHz with 384MB at the time, IIRC, for
recording, ripping, processing and burning.)

Cheers,
David.

This should start the FreeBSD installer.  You can set the root password 
to whatever you want.  You can add users with whatever usernames, 
passwords, etc., you want.



When done with the installer, choose Machine -> ACPI Shutdown.


Then change virtual machine settings to remove virtual installation 
media from VM:


Storage



Take a snapshot of the VM so that you can easily get back to the fresh 
installed state if and when desired.  (Going forward, take snapshots 
periodically and as desired.)



(Adjust other settings as desired, such as CPU cores.)


The next time you start the VM, you should see the console and login 
prompt of your new FreeBSD VM.




My impression is that since the Virtual Machine boots an ISO it
has not been configured with a user account and password. How then
can I log in at the login prompt?



My guess is that you booted a FreeBSD "Live CD" (?).  If so, STFW 
"freebsd live username password" I found:

"To gain access to the system, authentication is required. The username

Make sure you use the -a to append the new group to your existing groups or

Too many layers and possibilities to give a comprehensive listing.
Let's pick ONE.  Plain ALSA, without Pulseaudio or anything else on
top of it.

ALSA is implemented in the kernel, and the visible connection points
to it are character device files:

unicorn:~$ ls -l /dev/snd/
total 0
drwxr-xr-x  2 root root   60 Aug 16 07:35 by-id/

crw-rw+ 1 root audio 116,  1 Aug 16 07:35 seq
crw-rw+ 1 root audio 116, 33 Aug 16 07:35 timer

As you can see, members of group 'audio' can write to these things, and
can therefore cause the computer to emit sounds, or to stop emitting them.

But that's not how it normally works in modern Debian.

Do you see the '+' signs after the permissions?  Those indicate that
there's more going on than can be shown in the standard Unix permission
bits.  In this case, there's an ACL.  We can see it with getfacl(1)
(from the 'acl' package):

unicorn:~$ getfacl /dev/snd/pcmC0D0p
getfacl: Removing leading '/' from absolute path names
# file: dev/snd/pcmC0D0p
# owner: root
# group: audio
user::rw-
user:greg:rw-
group::rw-
mask::rw-
other::---


The 'user:greg:rw-' part indicates that my login name has been added to
the Access Control List for this file.  I can do stuff with it, even
if I'm not in the 'audio' group.  (I happen to be in that group, but
that's not important here.)

So... why am I in this ACL on this file?  Because when I logged in,
something added me to a bunch of ACLs on my behalf.  It's all part of the
complex login procedure on modern Debian systems.  I can't tell you off
the top of my head which program or service does it, but something does.

When I logout, presumably this ACL entry will be removed, and I would
no longer have access to those files, if I weren't in the 'audio' group.

If another user logs in, they'll get a similar ACL entry on the audio
device files, and they'll be able to play sounds also -- until they
logout, at which time their sound-making privileges are revoked.
They don't need to be added to the 'audio' group, and in fact, they
shouldn't be.  That's reserved for special users, like the one who
installed Debian (UID 1000).  On my system, that user is 'greg'.

I sort of understand permissions for files but I'm not understanding 
permissions for streams whatever that is.
I'm just requesting some comprehensible, simple to understand, overview

I get to the text/graphics menu with Debian logo and all.

I really wonder what on your system can confuse GRUB, so that it does not
get to the file /boot/grub/grub.cfg of the ISO which contains the menu

Mijn vorige run was meer dan vier maanden en ging mijn versie ook

The "Permission denied" arises when creating the file, not when reading the

Maybe the directory lacks of the required permissions, where you're unpacking.

Look at which file it's complaining about.

The file that it's complaining about ends with .img not .img.xz -- it's
the *output file* that's in the way, or else the directory you're in
is not writable by you.

The input file is not the problem.

Greetings all;

One of my Dell's, running buster has blown its video. It my 3d printer 
slicer running cura.


I have a couple older rock64 v2's w/4gigs of ram that I last ran armbian

wound up using an rpi4b instead. One of the rock64's ought to run 
octoprint to drive my farm.


So I download the latest stable armbian xfce desktop. But xz can't 
unpack the .img,

-dc or -dl ok, but not unpack. It would unpack to something over 6GB.

All attempts to unpack it are "no permission."
Its on a raid10, so there's a couple terabytes of room to play in.

I don't see much discussion about libvirt on debian-use, which I presume is
KVM/Qemu VMs. That means one of two things: either 1) no one is using it, or
2) it works so well it is good enough for the real world and no one needs to ask
questions about it on debian-user.

My advice - buy your Silent PC, Install Debian on it, and use KVM/Qemu on it
to install Windows. That will use supported Debian free software to provide the
virtualization environment for your Windows installation. If for some reason
KVM/Qemu/libvirt does not work, then install Windows Pro on the Silent PC
and run Debian in Hyper-V. AFAIK, MS fully supports Debian in Hyper-V, and that
would also most likely be a reliable setup also for the real world to run 
Debian 11
and Windows 10/11 simultaneously.

question about sound

[mick.crane]

hello,
Please take into account I don't know what I'm doing generally and know 
nothing about audio.
Several years ago somebody asked me to edit a radio broadcast to 
separate out a few seconds.
It took a couple of minutes to install Audacity, figure out the GUI 
thing and save the bits of audio.

I'm wanting now to edit .wav files.
Can't find Audacity in the repository for Bookworm.
There is Ardour6.
It's a bit complex.
By selecting PulseAudio as the wotsit it seemed to be working but I try 
again and there is no sound output to hear.

There is message like " don't have permission to access".
Is there some numpty explanation of how this is supposed to work ?
Do these things PulseAudio, Alsa, Jack provide a stream on some bus or 
something and the Ardour6 programme edits bits out as it goes by ?
If it's a physical piece of tape you can imagine you can cut it with a 
pair of scissors and cellotape bits together but I've no idea how it's 
working with a PC.

resource of simplified explanation appreciated.

regards

mick

At this point, that would be a FreeBSD question. Let's see if we

I have this working now with Xen/Qemu, Deb 11, and Windows 10, but I would not 
recommend
that for the real world, since sometimes updates and such break it. I don't 
know about VMware
on Debian, I suppose it might work, you can inquire with VMware to see how much 
support they
provide for VMware on Debian. Also, KVM/Qemu users might be able to weigh in 
with how
viable that is as an option to run Windows in a VM on Debian for the real word. 
And the
other option I know about is Virtualbox, which I also think can run on Debian 
and supports
Windows VMs.

I now tried in quemu
  
https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/weekly-builds/amd64/iso-cd/firmware-testing-amd64-netinst.iso

  qemu-system-x86_64 -enable-kvm -m 512 \
 -bios /usr/share/ovmf/OVMF.fd \
 -hda firmware-testing-amd64-netinst.iso

Offering the ISO as -hda is supposed to trigger the same boot path as
a USB stick at a real machine.
This run gives me a text/graphical menu with Debian logo, mentioning of
"UEFI" and "GRUB" and some offers to install Debian. I.e.
GRUB found the storage device with the ISO and loaded its configuration.


In your case i assume that this search does not yield success.

Inspecting the content of the EFI partition of the ISO
  mount firmware-testing-amd64-netinst.iso /mnt/iso
  mount /mnt/iso/boot/grub/efi.img /mnt/fat
i see the search in file /mnt/fat/efi/debian/grub.cfg :

  search --file --set=root /.disk/info
  set prefix=($root)/boot/grub
  source $prefix/x86_64-efi/grub.cfg

So if my theory is right, GRUB failed to find a filesystem with file
  /.disk/info
The interesting question is why.

Does your downloaded ISO behave differently with above qemu run ?

loging into virtual machine

I've installed virutalBox and downloaded  a FreeBSD ISO file. I 
created virtual machine for the FreeBSD. When I start it it boots to a

Hi Thomas, thanks for your answer.

What i took is not a live iso but instead it's the installer iso. 
Anyway, in the meantime another weekly build was uploaded, the last 
monday, and with that I was able to complete the installation.


Well, actually I had to type the same commands to boot the iso as the 
installer still doesn't run automagically, but this build doesn't stop 
at hard drives detection like the former. At the first run it stopped at 
the step where it tries to configure network mirrors, but since this is 
an up to date iso it doesn't matter much: i've just rebooted and told it 
to go on without mirrors ;)

Given that you mention "weekly build" i guess that you got Debian Installer

Thanks, at least now i know where i should file the report if it'll

Het hangt ervan af, maar meestal hoef je niet direct te rebooten al zou ik er 
ook geen maanden mee wachten.

Op https://www.debian.org/security/ zal je van tijd tot tijd ook een DSA zien 
over 'linux' en dan *kan* het verstandig zijn om zsm te rebooten.
Maar dat hangt ervan af of je mogelijk last kan hebben van die security 
issues. Een machine die rechtstreeks (en continue) aan het internet is 
verbonden is uiteraard kwetsbaarder dan een machine die niet altijd aan staat 
en waar eerst door andere devices (bv router) heen gebroken moet worden om 
jouw kernel 'aan te vallen'.
En het kan ook zijn dat de security issues helemaal niet op jou van toepassing 
zijn.

Daarnaast zijn er ook andere bug fixes waar meestal geen haast is om die toe te 
passen (door te rebooten), behalve als je zelf last hebt van een bug die 
gefixed is in die nieuwe kernel versie.

Met 'aptitude changelog linux-image-5.10.0-17-amd64' krijg je een lijst te 
zien met alle wijzigingen die zijn toegepast en je kan die bekijken om te 
bepalen hoe belangrijk die update voor jou is.
Via https://tracker.debian.org/pkg/linux kan je het ook zien, maar dat is vaak 
iets moeilijker omdat je niet direct het '-17' (ABI versie 17) deel ziet. In 
het specifieke news item zie je (meestal onderaan) iets als "Bump ABI to 17".

I used to run Windows in a commercially licensed VMWare environment for 
my business. I also have used VirtualBox for years for the same purpose. 
However, a couple of years back I switched to libvirt and never had any 
problems with it (that weren't of my own doing).


It *does* take a bit more time to really understand all the features, 
but it is worth your time. There is good documentation available, but I 
had to read some of it multiple times to get my head around it. Not 
because the docs were bad, but it is complex and written for people that 
already do have some experience in that area (I feel). There is a 
separate GUI, if you think that suits your needs (with the imaginative 
name Virtual Machine Manager).


I run a fully patched Windows 10 Pro in libvirt at the moment on a 
machine with 32 cores and 64 GB of RAM and it is speedy and stable 
enough for my needs (hosting a learning environment for my students).


I'd say: give it a go!

Re: Windows on VMware on Deb 11: safely usable?

[Jeremy Ardley]

I have Windows client on Debian and Windows Hosts using Virtualbox. I 
don't think there is much difference to VMWare for simple client hosting.


When the client is fully 'settled in' performance is perfectly adequate. 
Where it runs into problems is saving state and restoring. That is 
pretty fast, but if you save state and restore a few days later the 
client performance is abysmal for some time as the client goes through 
lots of housekeeping, scanning etc to get up to date. I generally 
restore it and go off and do something else for 30 minutes.


As an aside, a Windows host for a client sucks big time. Windows will 
automatically restart periodically no matter what you do to prevent it. 
When it does it's likely to smash the client and lose whatever you were 
doing.
