Dotaz: Bluetooth/chromecast zvukovka z raspberrypi bez grafického prostředi

[lertimir]

Řeším, jak odeslat zvuk z RPI do soundbaru TCL 8132. Je to fakticky pokračování tohoto dotazu, ale zatím jsem nedorazil úspěšně do konce. Konektivita soundbaru je bluetooth a chromecast. RPI je zcela bez grafiky, má základní instalaci a servery. Mé znalosti jsou v současnosti následující:

• Chromecast: Nejsem schopen se připojit ani s notebooku, mkchromecast -d mi i když je soundbar zapnutý zařízení neidentifikuje, a pokud jsem s wiresharkem trasoval pakety, tak notebook poslal multicast paket s dotazem a odpověděla televize, ale ne soundbar. Přičemž android mobil soundbar vidí a může ovládat, a proces s Androidem byla jediná cesta podle návodu jak ten Chromecast rozběhnout. Přesněji jednou se mi podařilo ten soundbar dostat do stavu, že jsem jej příkazem mkchromecast -d viděl, ale asi za dvě minuty mi zmizel. Takže asi neumím používat mkchromecast. nebo se neumím domluvit s zařízením
• Bluetooth: Mohu se připojit z notebooku a mít to jako zvukovku k notebooku. Raspberry umožní bluetoothctl pair a tust, ale bluetooth connect XX:XX... dá Failed to connect: org.bluez.Error.Failed. Hledal jsem a nalezl jsem radu Stejně jako v popisu se mi objevuje chyba src/service.c:btd_service_connect() a2dp-sink profile connect failed for 2C:FD:B3:4B:B3:16: Protocol not available, ale snaha podle popisu končí

  pactl load-module module-bluetooth-discover
  Connection failure: Connection refused
  pa_context_connect() failed: Connection refused

  Ještě jsem našel tento návod, ale jestli je to tak jak zde píší, tak potřebuji grafiku a X-ka a nic takové na RPI nemám. je to možné prolomit?

Celkově bych raději cestu prolomil přes wifi/chromecast proto, že bude lepší pro vyšší tok.

Tady je něco o Raspberry a Bluetooth v consoli. https://linuxhint.com/setup-bluetooth-raspberry-pi/

Prošel jsem to celé a connect dopadne takto

odpojení proběhlo asi za 10 vteřin po připojení a divné je, že mám úplně jinou MAC než mnohokrát předtím. Po odpojení už žádný scan.

Niektoré zariadenia mali tlačítko ktoré povoľovalo párovanie. Nebude to tento prípad? Pri BT slúchadlách a reprákoch to bolo štandardom nech náhodou sused nezačne robiť diskotéku u niekoho iného.

[lertimir]

Ano, na soundbaru je spuštění BT párování. Sounbar se správně spáruje s RPI, pípne na potvrzení, ale pak se nekonektně.

Pro připojení Raspberry Pi k soundbaru pomocí Chromecast byste měli použít nástroj mkchromecast, který umožňuje streamovat audio z Raspberry Pi na Chromecast. Vyžaduje ale, abyste měli grafické prostředí na Raspberry Pi a spuštěné X11 pro zobrazování dialogových oken.

Pokud nemáte grafické prostředí na Raspberry Pi, můžete vyzkoušet některé z ostatních možností, jako je připojení pomocí Bluetooth nebo pomocí protokolu RDP pro vzdálené připojení k grafickému prostředí na Raspberry Pi a spuštění mkchromecast přes toto připojení.

Pokud se vám ale nedaří připojit Chromecast pomocí mkchromecast ani s notebookem, může to být způsobeno několika faktory, jako je špatná kompatibilita s vaším zařízením nebo chybné nastavení Chromecast. Může být také vhodné zkontrolovat, zda máte aktuální verzi mkchromecast a zda jste provedli všechna nutná nastavení pro spuštění Chromecast, jako je například připojení k stejné síti WiFi jako Chromecast.

Pokud se vám nedaří připojit soundbar pomocí Bluetooth, může to být způsobeno tím, že Raspberry Pi nemá podporu pro Bluetooth audio sink (přijímač zvuku). Můžete to zkusit opravit pomocí následujících příkazů, které nainstalují potřebné balíčky a přidají podporu pro Bluetooth audio sink:

sudo apt-get update
sudo apt-get install bluez pulseaudio-module-bluetooth
sudo cp /etc/bluetooth/audio.conf /etc/bluetooth/audio.conf.bak
echo 'Enable=Source,Sink,Media,Socket' | sudo tee /etc/bluetooth/audio.conf

Poté byste měli být schopni připojit soundbar pomocí příkazu bluetoothctl connect XX:XX:XX:XX:XX:XX, kde XX:XX:XX:XX:XX:XX je vaše MAC adresa.
