…ction A user reported that sometimes the client log gets spammed with repeated messages such as: <W>2025-01-10 10:24:10.638 ALSAAudioInput: No such device: No such device The error corresponds to ENODEV (19), which we treat like any other. Since it's unrecoverable, the code gets stuck in a full speed loop until the audio engine is stopped. This commit: 1. Switches from snd_pcm_prepare() to snd_pcm_recover(), which is specifically designed to recover streams. 2. Breaks the loop if the error is not one of the only three recoverable (EINTR, EPIPE, ESTRPIPE). Example log: <W>2025-01-14 06:16:44.494 ALSAAudioInput encountered unrecoverable error: File descriptor in bad state -> exiting... Please note that also ALSAAudioOutput doesn't explicitly handle fatal errors in its loop, but it shouldn't run "infinitely" at full speed because poll-based. (cherry picked from commit d2dfcd3)
