SSM 2602 ALSA config

On a BF548 EZ-Kit I have this ALSA config and it looks good:

 

--------------------------------------- device #0

Name                        = bf5xx-board:  (hw:0,0)

Host API                    = ALSA

Max inputs = 2, Max outputs = 2

Default low input latency   =    0.011

Default low output latency  =    0.011

Default high input latency  =    0.043

Default high output latency =    0.043

Default sample rate         = 48000.00

Supported standard sample rates

for half-duplex 16 bit 2 channel input =

        48000.00

Supported standard sample rates

for half-duplex 16 bit 2 channel output =

        48000.00

Supported standard sample rates

for full-duplex 16 bit 2 channel input, 2 channel output =

......

 

Using the SSM2602, I have this and notice the default sample rate as compared to the supported sample rate:

--------------------------------------- device #0

Name                        = bfin-ssm2602:  (hw:0,0)

Host API                    = ALSA

Max inputs = 2, Max outputs = 2

Default low input latency   =    0.012

Default low output latency  =    0.012

Default high input latency  =    0.046

Default high output latency =    0.046

Default sample rate         = 44100.00

Supported standard sample rates

for half-duplex 16 bit 2 channel input =

         8000.00, 48000.00, 96000.00

Supported standard sample rates

for half-duplex 16 bit 2 channel output =

         8000.00, 48000.00, 96000.00

Supported standard sample rates

for full-duplex 16 bit 2 channel input, 2 channel output =

         8000.00, 48000.00, 96000.00

.....

 

Is that a deficiency of 44100 vs 48000 in the ALSA config?  This is 2011R1-RC3.  Any idea on how to change it?
