Pulseaudio server for playing 32-bit chroot sounds on 64-bit host machine

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Thank you both Lennart and Colin for your continued assistance.

I know /tmp IS being shared, that's why I can see two different 
/tmp/pulse-XXXX folders being created when I try to use paplay from 
within the 32-bit chroot. The relevant lines I run are:-

        mount --bind /proc /opt/arch32/proc
        mount --bind /proc/bus/usb /opt/arch32/proc/bus/usb
        mount --bind /dev /opt/arch32/dev
        mount --bind /dev/pts /opt/arch32/dev/pts
        mount --bind /dev/shm /opt/arch32/dev/shm
        mount --bind /sys /opt/arch32/sys
        mount --bind /tmp /opt/arch32/tmp
        mount --bind /home /opt/arch32/home

It's the weekend, and I won't be having access to that machine, so 
please forgive any delay in replies, I do appreciate your assistance.
