I just found out that my documentation about crypted debian installation had a static link to a version which is not up to date, this link will ever show the actual version (sorry): https://g3la.de/hedgedoc/buDIXGBuRzKMwUnYOpStuw#

Question for the audiphiles (like marcan ): I tried a bluetooth headset with pipewire/jack and ardour 6.7/debpack. But the dsp usage is blowing up. Any idea how this can happen? dsp is 2-3% with a scarlett usb d/a and the same setup. Looks like there is some additional cpu thingie with bluetooth audio?
<chadmed_>
your media is probably being transcoded on the fly to whatever codec your bluetooth headphones support
<chadmed_>
(bt headphones dont just take a PCM bitstream)
<Cy8aer[m]>
That is right but it does not need these ressources with an intel machine (Broadwell Laptop) and the same settings.
<Cy8aer[m]>
And there is no hardware codecs with intel too.
<Cy8aer[m]>
Ardour itself needs only a tenth of dsp ressources on the m1 than on the intel machine.
<Cy8aer[m]>
(setup with scarlett on the intel is about 20%)
<Cy8aer[m]>
And on the m1 it still works without any drops. So I wonder if there is some buffer communication blocking or it is not responding the right way.
<Cy8aer[m]>
The dsp message is more an error message than a percentage in Ardour (on the upper right corner)
<Cy8aer[m]>
Actual coding to the bt device is aptx (libfreeaptx)
<chadmed_>
its probably just the aptx implementation or something like that then
<Cy8aer[m]>
Hm, ok, I try other codecs lateron.

Cy8aer[m]: "DSP usage" is not a CPU usage meter (check your actual CPU usage)
<marcan>
DSP usage is relative to how much time there is in a processing cycle to complete DSP tasks on time
<marcan>
with something like bluetooth with high latency, who knows how that is being calculated
<marcan>
it could be you ended up with a ridiculously small buffer size causing actual high CPU usage, or that whatever backend contraption you're ending up with is not actually giving Ardour reasonable real-time processing time for whatever reason
<marcan>
bluetooth output isn't really intended for proaudio, and I doubt anyone really optimized/debugged that kind of audio path for this use case
<marcan>
you'd have to give details of exactly how you have your system configured (JACK/PA/etc and what Ardour backend) to try to reproduce it, but it might only happen with certain Bluetooth devices too since the codec plays a role
e1eph4nt has joined #asahi
<marcan>
could also just be that some kind of timestamping involved in the audio backend is broken for bluetooth
<marcan>
e.g. it reports playback timestamps in the past, and ardour thinks it's already late for the next cycle when it isn't
<marcan>
the bluetooth host controller hardware could be involved too, potentially
<marcan>
this stack is too deep, it could be anything
<marcan>
proaudio is hard enough when you don't throw in bluetooth into the mix ;)
<marcan>
good to hear it's way better than Intel with USB hardware though - that's what I was looking forward to
<marcan>
I bet that's a nice mix of the CPU just being better, and also much lower wake latencies
<marcan>
and ~zero throttling

Hi, sorry if this is the wrong place to ask but is there a way to reinstall Asahi? I want to switch from Gnome to KDE :)

@Cy8aer your asahi-fwextract.install does not end cleanly. At the very end "OSError: liblzfse.so: cannot open shared object file: No such file or directory" As far as I am aware liblzfse is a MACOS thingy.
<Ry_Darcy>
Also python3 -m asahi_firmware.update /boot/efi/asahi /boot/efi/vendorfw/firmware.tar.new /boot/efi/vendorfw/manifest.txt.new starts with "Traceback (most recent call last): File "/usr/lib/python3.10/runpy.py", line 196, in _run_module_as_main return _run_code(code, main_globals, None, File "/usr/lib/python3.10/runpy.py", line 86, in _run_code exec(code, run_globals) etc."

hi. small question. is known if the current state of the boot chain could work on a macbook air m2? i was greedy and decided to directly build my own kernel and it can't find any usb device
<j`ey>
that should work, sounds like a config issue?
<waldi>
well, just asking, as the blog post only talked about untested support for this machine and i found no reports that it actually would work
<waldi>
and i might have out-of-date u-boot anyway
<j`ey>
well your issue seemed to be about the kernel?
eroux_ has joined #asahi
<jannau>
at this point the "unsupported" is mostly about the macos stub/firmware. no promises that we will support the firmware shipped with macos 12.4
<jannau>
usb should have always worked on m2 (usb 2 only)
<jannau>
the other issue at the time of the blog post was keyboard/touchpad support but that should be sorted now

okay. anyway, now i have a working baseline. and a u-boot with keyboard input. thx for you help

ok, I think this is the worst ghetto hack I've ever resorted to. I don't have speakers right now and just built a desktop. my headset gets uncomfortable after a while. Have my macbook parsec'd into my desktop for audio 🤣

simple question.. what 'version' of asahi gets pulled by running the curl command to install? Will it pull a static alpha version or from the latest arch/git repository?
