Must be an old version of xmms? It swaps bytes if necessary since 1.2.5
or so.

What are those apps? In my experience, most apps where sound doesn't
work are simply broken and need to be fixed anyhow, no kernel patch can
help that.

For example, the XMMS cdread plugin needs fixing to convert the data to
native endianness anyway because otherwise the filtering for the XMMS EQ
produces noise again.
