[Asterisk-Users] noises an Zap channel (TDM20B) while hdd activity

[Dave Packham]

I have a 4 port card in a regular system and I get that prob sometimes when I copy large files to that server....  IRQ problem?  if I stop the copy the sound prob goes away.  not a big help but at least you know that your not alone...

Sounds like underpowered power supply. Small machines are not known for
having quality hard working power supplies, and With the need for some
extra power on the TDM cards it is possible your power supply is not up
to the task. Couple that with the problem of finding another power
supply that will fit in that machine, you may have to use a full size
system.
