You can read /proc/asound/cards file also to see available cards.

Thanks for the tips guys!

I've tried to use /proc/asound/cards, but it allready contained the soundcard during boot allthough it wasn't available.
The aplay-l trick worked! I've made statement that checked if the command was successfull.

But then I realized that I could do the same trick with "alsactl restore".  :)
So I ended up with this command, which seems to work pretty good:


--- Code: ---for i in $(seq 1 15); do alsactl restore && break || sleep 0.1; done
--- End code ---

It tries to execute the command for 15 times, and sleeps 0.1 second in between tries.
Normally it succeeds after 2 or 3 tries.

I've also got a version that adds some logging to a logfile:

--- Code: ---for i in $(seq 1 15); do alsactl restore && break || sleep 0.1; echo "alsactl restore, #tries: $i" >> /tmp/log.txt; done
--- End code ---

I think I've rebooted my raspberry pi for about a trillion times this evening while creating this...  ;) ;D

USB sound card?
add waitusb=5 to cmdline.txt

I need to wait for usb drives to get ready, maybe it's the same with usb sound cards?

I usually have to stick sleep times loops in bootsync.sh for the network to find ip address, date etc

Hi gavinmc42

A loop like this will wait until the network is up:

--- Code: ---SEC=60
while [ $SEC -gt 0 ] ; do
   ifconfig | grep -q "Bcast" && break || sleep 1
   echo -ne "Waiting for IP $((SEC--))  \r"     
done                                       
echo
--- End code ---

Hi Béla,

I have managed to boot, is there any way to get to GUI? I tried to download TC but server does not respond, getting an error.

I have pi3 model B, does any other version of picore with GUI support this model?

Kind regards
