The component does not load in HASS v0.115.3

[eugenet8k]

I put the component into custome_components and configured the media-player entries, but upon HASS restart it gives me this error in logs:

I found the following solution:

1. Install aiokef directly into OS where HomeAssistant is running, because some dependencies are missing:

> pip3 install aiokef

2. update media_player.py from this repo.

Replace

from custom_components.kef_custom.aiokef import (
    AsyncKefSpeaker,
    DSP_OPTION_MAPPING,
)

with

from aiokef import AsyncKefSpeaker

def arange(start, end, step):
    return [x * step for x in range(int(start / step), int(end / step) + 1)]

# DSP options
_DESK_WALL_DB_OPTIONS = arange(-6, 0, 0.5)
_TREBLE_DB_OPTIONS = arange(-2, 2, 0.5)
_HIGH_HZ_OPTIONS = arange(50, 120, 5)
_LOW_HZ_OPTIONS = arange(40, 250, 5)
_SUB_DB_OPTIONS = arange(-10, 10, 1)

DSP_OPTION_MAPPING = {
    "desk_db": _DESK_WALL_DB_OPTIONS,
    "wall_db": _DESK_WALL_DB_OPTIONS,
    "treble_db": _TREBLE_DB_OPTIONS,
    "high_hz": _HIGH_HZ_OPTIONS,
    "low_hz": _LOW_HZ_OPTIONS,
    "sub_db": _SUB_DB_OPTIONS,
}

And also, replace MediaPlayerDevice with MediaPlayerEntity, to avoid HASS warning of deprecation.

And also, replace ioloop into loop all over the file

    media_player = KefMediaPlayer(
        name,
        host,
        port,
        maximum_volume,
        volume_step,
        standby_time,
        inverse_speaker_mode,
        supports_on,
        sources,
        loop=hass.loop,
        unique_id=unique_id,
    )

That made it start with HASS, and I am able to control my KEF LSX. I guess I might just do a fork of this repo.

@basnijholt oh, what the hell! I was searching for one and couldn't find anything... Truly blind I was! I guess it's not in the Integrations catalog yet.

@basnijholt maybe, if that makes sense, it would be reasonable to have some top-level comment in this repo README.md. That this is a deprecated repo and we should just use the official HASS component. Thanks for pointing it out!
