echo24 driver: no support for 24 bit and 96kHz sample rate

[nutela]

The sound card is an Echo Mia MIDI. With the Haiku multiaudio media addon and Echo driver of release 21093. I expect to use the cards all available sample and bit rates but most important is 24 bit and 96kHz sample rate support. (nice job nevertheless!)

The driver had a problem when handling echo.settings parameters. It works for me in hrev22788 with playback 24bit/96kHz. Was recording your concern too ?

[nutela]

Just as a reminder that the sound was indeed very garbled when I recorded some material @ BeGeistert 018 but that was under R5 not Haiku. Is there any other app which can record from line in? Maybe it is BeOS soundrecorder which is misbehaving.

I don't have any 24 bit files, how do you know 24 bit 96kHz works?

[korli]

24 bits recording shouldn't work. Only 16 bits.

Here you can find test sound files: ​http://www-mmsp.ece.mcgill.ca/Documents/AudioFormats/WAVE/Samples.html

Changed subject to better summarize. Will make a separate bug for recording.

When I try to play back with MediaPlayer: M1F1-int32-AFsp.wav M1F1-int32WE-AFsp.wav M1F1-int24WE-AFsp.wav M1F1-int24-AFsp.wav playback is silent(, the files with "float" in their names report unsported codec by MediaPlayer.)

And setting echo.settings to 24 bit, sample rate 96000 makes 16 bit 44.1khz files play back badly with a lot of 'aliasing'-like distortion. Setting echo.settings too 24 bit, 44100 solves it. Some resampling done in Haiku or driver?

[korli]

It seems MediaPlayer doesn't support playing 24bits wave files. Could you try with the "playfile" command please ?

[korli]

Should be fixed in hrev31760.
