When writing to /dev/sound/midi00 in alsa 0.9.0beta10, my computer
freezes. It still responds to pings, but anything else is a no go. There

computer.
I have a cs4237b, and compiled the driver with gcc 2.95.3 and binutils
2.11.90.0

I've noticed that a lot of the cards ALSA supports are capable of four
or more channel audio. However, in at least two cases that I've
investigated in depth, the driver supports only two channels (maestro3
and cs46xx).
Why is the four-channel sound capability of these cards not implemented?

a "hw" device is totally constrained by the hardware characteristics
of the underlying audio interface. if the device has 26 channels, then
it must be used with 26 channels; if i
Hi!
I'm porting my application from ALSA-0.5 to ALSA-0.9 and I don't
understand ASCII identifier of the PCM handle which is
a parameter of the snd_pcm_open function.
I'd like to implement an user friendly sound card configuration
dialog. This is a screenshot of the previous one:
