It would be good to have a Tested-by: from Rick.
If someone will make a .deb I can download, I'll be happy to install it and test it. Please be explicit in describing what and how you want tested.
Check your email. :)

Got it.
Looks like mmc works with that kernel. I was able to mount /dev/mmcblk0p1 and read files from it.
Sound we have some progress:

Full of hope, I did "aptitude install mp321" which went without any visible problems.
Then hooked up a pair of earphones to the "speaker" plug on the Client and ran

So it seemed to be running OK... But there was no sound in the earphones. I also tried adding option "-g 50" to set the gain explicitly. Still no sound.
Is there a hardware jumper I need to set to activate sound on the OpenRD Client board?
Do I need to install another package? For example, "aptitude search '~i alsa'" gives no output, indicating, I believe, that there are no installed packages with "alsa" in their name.
The message:
ALSA lib pcm.c:2267:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.front
seems suspicious.
Any thoughts? Rick
