I can make sof-test/test-case/check-playback.sh run on ChromeOS, but there are some issues.
terminal.txt

1. the visudo configuration seems only takes effect once.
2. there is no /var/log/kern.log file.
3. the sudo funciton in hijack.sh report a library issue, but the file does exist on the system.

dmesg: error while loading shared libraries: libtinfow.so.6: cannot open shared object file: No such file or directory

4. no sudo group on ChromeOS
5. we have to specify bash or python3 when run shell/python scripts, check https://chromium.googlesource.com/chromiumos/docs/+/master/security/noexec_shell_scripts.md
6. journalctl require root permission

How dependencies are installed?

• I found a package management tool named chromebrew, this tool can help to install dependencies as apt did for us.
• python3 dependencies should be installed with pip3
• this tool can not run with root.
