I am not sure about your specific setup. But PA allows you to specify an explicit channel map for an alsa sink. Also, PA takes negotiates the channel map with its clients. So, which client are you using? If you access PA through ALSA, then I guess I can only say I am sorry: ALSA does not support negotiating channel maps. For ALSA you need to *know* the channel map of a device. Lennart -- Lennart Poettering Red Hat, Inc. lennart [at] poettering [dot] net ICQ# 11060553 http://0pointer.net/lennart/ GnuPG 0x1A015CC4
