samples/bluetooth/unicast_audio_server doesn't configure heap memory for IPC

Confirmed to be an issue. Thanks for the report

Hi @yclistanford while I could reproduce an issue, it is not the same as you do.
There was an issue with IPC, but it was not related to heap, but rather some BT buffer sizes. These have been fixed by #72861.

After the above PR, I can no longer reproduce any issues given the steps in this issue. Can you try to apply the changes from #72861 to your build and see if there is still an issue?

@yclistanford PLease respond, else this issue will be closed.

Yes I did need the BT buffer sizes in #72861. That's a separate issue. For the heap mem pool size, the sample has CONFIG_HEAP_MEM_POOL_ADD_SIZE_BOARD=4096 and that should become K_HEAP_MEM_POOL_SIZE (calculation is in kernel/CMakeLists.txt). For some reason that did not happen for me in my previous build. I will close this issue.

Thanks.

The CONFIG_HEAP_MEM_POOL_ADD_SIZE_BOARD is not set by the sample itself, but rather with the board. So if you encounter issues with this value, it's likely an issue with the specific board you are compiling for, rather than the sample :)
