Audio codec using 100% of the CPU all the time.
Hey guys, I'm having this annoying problem that some other people reported.
My hwC0D0 audio codec is using 100% of my cpu all the time.
I tried every solution I could find online but nothing worked, can someone give an advice? Thanks in advance!

Re: Audio codec using 100% of the CPU all the time.
1. Connect to the process using "strace -f -p $PID" it will show you what syscalls the app does. If it repeatedly polls/reads content of some file then it might give you a clue what is going on there.
2. Recompile the package with "debug" symbols on. The profile the app with perf tool: "perf top -p $PID". It will show where CPU cycles are spent. It might be some kind of infinite loop bug.
In any case please report this info to upstream developers.
