sendspin daemon --audio-device "my_alsa_device" should not try reaching a pulseaudio server

Start in sendspin/cli.py at _run_client_mode and then inspect sendspin/audio_devices.py, where sounddevice is imported and the audio device is resolved. Reproduce the command with the ALSA device from the report on a system without PulseAudio. Done means selecting that device no longer attempts to connect to a PulseAudio server.

Env:

• Kernel/Arch: 6.18.38-current-sunxi / armv7l
• OS: Ubuntu 26.04
• sendpin-cli 7.5.0
• No Pulseaudio software installed or running.

Steps

$ /root/.local/bin/sendspin daemon --log-level DEBUG --name "P0" --audio-device "plughw:CARD=Lite,DEV=0" --hardware-volume true

Note: plughw:CARD=Lite,DEV=0 is a ALSA device.
