Ok, so the speaker is muted.  The 'normal' IBM/Lenovo sound up/down/mute 
buttons don't do anything?  If so that's possibly an ACPI / BIOS issue I 
know nothing about.  It is running acpi_ibm.ko I suppose?  If so, what 
does 'sysctl dev.acpi_ibm' have to say?

That's all you'll see, indicating relevant performance|economy settings 
for cx_lowest and cpu_freq from /etc/defaults/rc.conf being applied.

I have a T500 on loan with broken keyboard.  If I get that fixed or find 
a USB keyboard this week I'll check if it behaves the same as your T530.

Good luck, Ian
