Do you just mean whistling while breathing in and also while breathing out? I can do that, but there’s a short break in the whistle when I switch the airflow direction.

Ie I can whistle a long song without pause, but I can’t whistle a single sustained note without a short but noticeable break in the sustain when I switch from breathing out to breathing in and vice versa.

I’ve only personally used the tizen app a couple times, but my relatives have used it a bunch with no reported issues. I have not had to update it yet, but it’s only been a few months. Definitely not frequent updates. My jellyfin server has had one update since then, but even the server updates aren’t coming in on a weekly basis, so I don’t expect their client will break anytime soon.

It’s not super easy, but you can install it on tizen tvs by enabling developer mode. I was able to follow this walk-through to get it on a new TV for my relatives.

Since their TV was newer, I had to do extra steps to create a custom certificate.

The whole process took a while, but it’s doable.
