Now I know that Matlab will say if you try to use the audiorecorder function, and specify 24 bits in linux, it will tell you that 24bit is only supported in Windows. However the ALSA literature does not imply that this is a limitation of the operating system or of ALSA itself, and as a matter of fact Alsa seems to allow you to specify a 24 bit PCM device.
