Problem: how do I change byte order options?
I was afraid you would ask me that, and I was hoping that some other reader
would jump in before you did telling you what they are.
Anyway, man aplay
-f --format=FORMAT
Sample format
Recognized sample formats are: S8 U8 S16_LE S16_BE U16_LE U16_BE
S24_LE S24_BE U24_LE U24_BE S32_LE S32_BE U32_LE U32_BE FLOAT_LE
FLOAT_BE FLOAT64_LE FLOAT64_BE IEC958_SUBFRAME_LE IEC958_SUBâ??
FRAME_BE MU_LAW A_LAW IMA_ADPCM MPEG GSM
Some of these may not be available on selected hardware
There are also two format shortcuts available:
-f cd (16 bit little endian, 44100, stereo [-f S16_LE -c2 -r44100]
-f dat (16 bit little endian, 48000, stereo) [-f S16_LE -c2 -r48000]
If no format is given U8 is used.
Anyway, try first
aplay -f cd whatever.wav
Then try
-f S16_BE -c2 -r44100
as a .wav option.
(.wav files should alread have the information, so instead try
cat whatever.wav|aplay -f S16_BE -c2 -r44100

Hey, I recently purchased a usb dock from Kensington which includes 5.1
audio support. This was the feature that I most wanted it for. Anyway, I
have been unable to get alsa to use it. Alsa recognizes it as usb audio,
and
when I test it, all I get is crazy static. Anyway, it is a C-media cm106
Sounds like a byte order problem. Try the various alsa byte order options
to aplay. It is very hopeful taht you are getting sound out of it. That
means it workd and all you need is some tweaking.
like sound device. Any help? Also, I am very new on the linux scene and
only
know how to do the most basic of terminal stuff.
