Check that the user you are trying to run mythtv as is a member of the audio group. You can check using the command "grep audio /etc/group". If the user isn't listed, you've found your problem. Add them to the group using the usermod command (i.e. "usermod -a -G audio username", replace username with the appropriate name).<div>

If I run as an ordinary user I get the error<br>

<br>
This has been documented before but if I try running the frontend SUID<br>
root then the BBC weather scripts fail due to perl getting huffy running<br>
as root.<br>
<br>
Is there a solution to this?<br>
