[alsa-devel] About 'SNDRV_PCM_CLASS_MULTI' for devices with multi-channels

Hi all,

I have two questions about the usage of this macro.

Should I use this macro for new drivers which I'm working for?' http://mailman.alsa-project.org/pipermail/alsa-devel/2014-January/071820.htm...

My drivers support some firewire devices, which is desinged for studio-use and have many channels. Its combination of channels are not designed for surround sound like 5.1ch.

Just judging from its name, 'SNDRV_PCM_CLASS_MULTI', I should use this. But there are no drivers which use this macro in current tree, against my expectation that some drivers (ICE1712-pro, RME9652, 6fire usb and so on) should use this macro.

Are there any reasons?
