FLAC at 24-bit per sample don't work

[John Saturday]

Some of my files are at 16-bit 44.1 kHz and some others at 24-bit 48 kHz... RAW PCM pipe stream without byte order, bits, sample rate and sign of samples is a big noise. Also command "flac -d -c --totally-silent -" output to pipe WAV !!! file not a RAW PCM.

Currently I tested with WAV pipe stream modification and report back if all OK:

backends.py
78: encode_command = [encoder_path, "--ignorelength", "-Q", "-b", str(bitrate), "-"]

decoders.py
30: 'flac': ("/usr/bin/flac", "-d", "-c", "--totally-silent"),
31: 'm4a': ("/usr/bin/faad", "-q", "-w"),
32: 'mp3': ("/usr/bin/mpg123", "-w", "-", "-q"),
33: 'ogg': ("/usr/bin/oggdec", "-Q", "-o", "-"),

Others idea is of using FFmpeg but this is a futures.
