Hi David, (My message was not delivered by ALSA's mailman...)
Again 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?
In current tree, there are no drivers which uses this macro.
As long as I investigated in ftp server, this macro is firstly added in ALSA 0.9.0beta1 (2001/02/21). So this macro has been ignored over 10 years...
