tbh the lack of audio is about the only thing putting me off from wanting to even touch linux on the switch. Either a lot of people don't care about audio, there's not that many people who use linux on the switch making it pointless, or there is something causing trouble that makes it difficult to get audio working. That's the way I see it.
I would think the introduction lakka.tv there would be more of a push to get audio but something must be wrong that is stoping this issue from being resolved
