Sound system(alsa) fails on resume from suspend

[Rob M]

Desktop system audio failure upon resume from suspend. Event occurs approx. 50% of time and can be remedied with sudo alsa reload. Firefox is program where problem is first noted but no sound from any source is working. Using GUI for sound setting will not correct problem.
