I am trying to use the alternate sample rate feature; I have checked that 
my device supports 44k1 and 48k sample rate in hardware (both for capture 
and playback)

when I set primary and alternate sample rate to the same value, 
everything is fine (either 48k or 44k1), however with primary 48k and 44k1 
alternate, the card fails to resume

the command I test is a loopback (just playback or capture works fine):
pacat -r -d alsa_input.platform-soc-audio.analog-stereo | pacat -p -d alsa_output.platform-soc-audio.analog-stereo

the statement that hw:0 doesn't support 44100 Hz is incorrect

I can work around by prohibiting suspend or by forcing to the alternate
rate to be the primary

is this supposed to work?
any ideas how to debug?

regards, p.
