Smart Filters: filter chain fails to relink on Pipewire
Currently, on the Steam Deck LCD, the speaker audio endpoint does not emit audio if you plug in an HDMI audio device and select the Speaker endpoint.
We only intend to use filter-chain-playback on the OLED, so we target the sof-nau8821-max
soundcard in policy.lua.d/30-filters-config.lua. This might mean that we are leaving filter-chain-playback unlinked to the speaker target.
We'd like to have an identical package and set of files that works with both the LCD and OLED skus if possible. Is there a good way to entirely disable the filter-chain-playback and virtual-sink when the soundcard we couple them with (sof-nau8821-max) isn't present?
