Audio lost on windows after session lock / user switch

[serpilliere]

The bug is triggered with the following steps:

• a user logs on a windows system
• launch sanzu_client (with sound)
• the user locks its session
• another user log into the machine (switch user)

The sanzu_client then loses its connection to the audio output. Windows seems to 'disconnect' the audio sound card (to give access to the new logged user)

If the second user disconnect and the first user re-login, sanzu still runs, but without sound.

The error is catch here:

sanzu/sanzu/src/sound.rs

Line 261 in aa769de

let err_fn = |err| error!("An error occurred on stream: {}", err);

We may mark the decoder as in error mode, which may later be catched in :

sanzu/sanzu/src/sound.rs

Line 304 in aa769de

pub fn push(&mut self, data: Vec<u8>) {

which in turn may be catched in the main code. This will allow the main process to be aware that the sound is in error state, and try to re init the sound output.
