echo24 driver; recording only 16 bit, 44.1kHz (R5), 16 bit, 44.1,48kHz (Haiku) + buggy

[nutela]

HW Echo Mia Midi

How to reproduce:
set echo.settings to any format not 16 bit, 44100 Hz in R5 or 16 bit, 44100 or 48000 Hz in Haiku, restart Media server

Experienced behavior:
Recording at different sample rates or bit depth produces severe distortion which sounds as severe aliasing, when booting from R5 to Haiku or reverse with settings 16 bit, 44100 Hz in R5 or 16 bit, 44100 or 48000 Hz in Haiku, recordings are always severely distorted in R5 for which a shutdown or reboot is needed, and sometimes the same happens in Haiku for which a media server restart is needed. Getting 48000 sample rate support for recording is difficult to reproduce, I had to uncheck or check the "4+" checkbox and/or randomly set different settings and restart the media server to fix it.

A note for testing: In R5 when recordings are recorded correctly they do not sound correctly in R5's SoundRecorder but lack the distortionduring playback in SoundRecorder , only clicks are heard, which are gone playing the same file in Soundplay or mediaplayer.

Expected behavior:
It would be nice to have all bit depths and sample rates supported by the hw have available in the driver as well, however much more important is consistent behaviour the fact that recordings made could be distorted/garbled for unknown reasons and restarting the media server doesn't solve anything in R5. When it does work it works excellent in R5 but Haiku is affected by another bug: #2787: clicks in audio with cpu activity, the clicks are recorded :(

If serial output is disabled, clicks shouldn't appear.
