Alesis io|2 usb soundcard kernel warnings sample rate

[Brent Hostetler <brenthostetler@xxxxxxxxx>]

Hello,

I am working through some sound issues with my usb sound card. It is
an alesis io2 express. It has a fixed sample rate of S24_3LE 48000.

I am not using a sound server.

99% of my apps are working perfect.

Each time a new sound/song is started I am getting a lot of noise in
my kernel logs like the following:
[86066.350459] 2:1:1: cannot get freq at ep 0x1
[86066.579352] 2:1:1: cannot get freq at ep 0x1
[87346.612367] 2:1:1: cannot get freq at ep 0x1
[92378.278333] 2:1:1: cannot get freq at ep 0x1
[93212.749706] 2:1:1: cannot get freq at ep 0x1

I would guess that this is related to probes for supported sample rates?

As a test I tried something like this my .asoundrc
pcm_slave.sl3 {
   pcm "hw:0,0"
   format S24_3LE
   channels 2
   rate 48000
}

pcm.testconv {
   type plug
   slave sl3
   hint {
      show on
      description "format and sample conversion"
   }
}

aplay -D testconv out.wav

same warning.

Tried playing a wav file converted to S24_3LE 48000. Same warning.

Any suggestions on what I need to config to get rid of this warning?

thanks.
