There is no hypervisor in Linux-VServer.
There is a kernel and a host system and a number of guests.

Try to run squeezelite with strace in a chroot into the guest
and see if the result differs.
If you get the same result, then the isolation (Linux-VServer
is not involved).
If it works inside the chroot but fails inside the guest, then
you might have insufficient capabilities.
In this case, upload the full strace from both, inside the
chroot and inside the guest somewhere and provide an URL.

Not from the Linux-VServer side, but it might have changed
in the kernel.
