I do not have arm-linux-gdb but have arm-none-linux-gnueabi-gdb.
But when use the command
./output/host/opt/ext-toolchain/bin/arm-none-linux-gnueabi-gdb -c core
./output/target/usr/bin/aplay and use command "run" the debugger show:
Don't know how to run.  Try "help target".

I think the problem is not in aply because I have the same problem with
mpg123.
Could be the library alsa?
