    Hi,

    In xawtv I *only* get sound on the right speaker.
    I don't have this problem in other programs; XMMS gives me sound on five
    speakers (as it should). When I play DVDs in xine all six speakers work (as
    it should).

    Is there a way to adjust the volume balance in xawtv?

    Is this a driver problem?
    Is this related to the order the drivers are loaded?
    http://lists.debian.org/debian-devel/2004/12/msg01841.html

    ------------------------
    # cat /proc/asound/cards
    0 [Bt878 ]: Bt87x - Brooktree Bt878
                         Brooktree Bt878 at 0xe4001000, irq 201
    ------------------------
    Does this mean the bttv driver is loaded before the sound card driver?

    I found this info page on ALSA in debian:
    http://wiki.debian.net/index.cgi?ALSA

    I find it is confusing... when it comes to setting the load order.
    How is the driver load order set (if that is the problem)?

    Thanks,
    Michael
