[alsa-devel] Problem calling "snd_pcm_hw_params_set_channels" with a RME 9652 (the same call -with more channels- works OK on a MADI one)

Hi all,

I have a problem with an application that worked OK on a RME Madi but 
now is failing with a 9652.
It fails calling to snd_pcm_hw_params_set_channels . With the 9652 i'm 
getting an error -22 "invalid argument", with any number of channels (I 
understand it should be 24 ?)

Any idea?

Alsa ver. : 1.0.24
Kernel: 3.0.4
/proc/asound/cards :
     0 [DSP            ]: H-DSP - Hammerfall DSP
                           RME Hammerfall HDSP 9652 at 0xfebf0000, irq 23

Thanks in advance,
