- add note that users are alarm/alarm and root/root
|
|
- Configure wpa_supplicant: create config (interface specific), start temporarily, use wpa_cli to configure wifi, enable systemd service (for specific interface, which requires specific config file created earlier)
|
|
- enable and start dhcpcd (systemd service)
|
|
- Enable bluetooth stuffs. see one of the latest comments [here](https://gist.github.com/shenghaoyang/92e6dd65b9f0cc736a419f3e640663c2)
|
|
Particularly where it says:
|
|
`So put dtparam=krnbt=on in your /boot/config.txt and hci0 should come up after boot,`
|
|
Scratch this, Wat uiteindelijk in de config.txt moet staan, want anders geen sound via broadcom:
|
|
```
|
|
# See /boot/overlays/README for all available options
|
|
dtparam=audio=on
|
|
|
|
dtoverlay=vc4-kms-v3d
|
|
dtparam=krnbt=on
|
|
initramfs initramfs-linux.img followkernel
|
|
```
|
|
|
|
- install bluez and bluez-utils. start and enable bluetooth service.
|
|
|
|
- Follow this again? https://gist.github.com/yejun/2c1a070a839b3a7b146ede8a998b5495
|
|
- Interesting note: installing just pulseaudio-bluetooth this time (before it was pulseaudio as a whole?) only took 94.20MiB this time. before it was something between .5 and 1 gigabyte
|
|
-> yes the pulse user is needed or pulseaudio will complain on it not being there (when run as a system service?)
|
|
-> I did everything except for alsa stuff (just the /boot/config.txt stuff did the trick i think to resolve issues i had earlier )
|
|
-> What i also did from this (https://didier.io/post/raspberrypi-stream-sound-over-bluetooth) is:
|
|
- In /etc/bluetooth/main.conf file, add Class = 0x00041C.
|
|
All the rest i tried did not seem to have effect and was reverted
|
|
|
|
- Go through the loops and hoops to pair a bluetooth device using bluetoothctl and make sure to add it to trusted devices (power on, scan or set discover on and pair/connect, trust)
|
|
|
|
Side note: messing with wrong clock (which was confusing in journalctl), this link seems interesting for various other things: https://gist.github.com/theramiyer/cb2b406128e54faa12c37e1a01f7ae15 but nothing about the clock
|
|
Configure time: rapsberry pi does not have a proper hardware clock, so we need to sync time using the interwebs (ntpd)
|
|
pacman -S ntp
|
|
systemctl enable ntpd
|
|
systemctl start ntpd
|
|
|
|
And set the right timezone
|
|
```ln -s /usr/share/zoneinfo/Europe/Brussels /etc/localtime```
|
|
|
|
|
|
Last state:
|
|
Audio sort of works and so does auto-connect (forgot to trust the device earlier) it is however popping and lagging a lot.
|
|
We're probably not using APT-X (as that seems to be done by replacing pulseaudio-bluetooth with pulseaudio-modules-bt AUR)
|
|
See the error handling section of: https://wiki.archlinux.org/title/Bluetooth_headset#Switch_between_HSP/HFP_and_A2DP_setting
|
|
neither can we switch to a2dp_sink so we're probably running as headset (speex codec shit?)
|
|
|
|
|
|
Continuation:
|
|
- Annoyed by pulseaudio not being controllabe due to system-wide service, i skimmed the arch wiki page on pulseaudio:
|
|
```
|
|
Then enable pulseaudio.service at the system level.
|
|
|
|
# systemctl enable --now pulseaudio
|
|
You will also need to disable the user-level pulseaudio service across the whole system:
|
|
|
|
# systemctl --global mask pulseaudio.socket
|
|
```
|
|
this however does not seem to be the issue of our crackling/popping sound...
|
|
And no solution for our pactl issues, appears that installing sudo helps so we are able to do this instead:
|
|
sudo -u pulse pactl
|
|
to run pactl and thus for example
|
|
sudo -u pulse pactl list
|
|
|
|
- Installing aptX support required building 'pulseaudio-modules-bt' from AUR. Which implies installing base-devel packages to be able to do so, and some extra dependencies
|
|
Once installed it automatically works, but unfortunately does not fix the sound glitches we have (popping/crackling)
|
|
|
|
- This fixed most of the crackling/popping. sound still feels a bit off and laggy. (from the arch wiki on pulseaudio, adapted for out system-wide usage of pulse)
|
|
Glitches, skips or crackling
|
|
The newer implementation of the PulseAudio sound server uses timer-based audio scheduling instead of the traditional, interrupt-driven approach.
|
|
|
|
Timer-based scheduling may expose issues in some ALSA drivers. On the other hand, other drivers might be glitchy without it on, so check to see what works on your system.
|
|
|
|
To turn timer-based scheduling off add tsched=0 in /etc/pulse/system.pa:
|
|
```
|
|
#/etc/pulse/system.pa
|
|
load-module module-udev-detect tsched=0
|
|
```

=> not fully working yet, trying some of this: https://didier.io/post/raspberrypi-stream-sound-over-bluetooth
|
|
mainly added Socket in audio.confg based on 'In /etc/bluetooth/input.conf file, add Enable=Source,Sink,Media,Socket.'
|
|
and In /etc/bluetooth/main.conf file, add Class = 0x00041C.
|
|
+ reboot

Still not workin! Bluetooth service zegt
