There still seems to be a problem with this device: hdac0@pci0:0:20:2: class=0x040300 card=0x30c2103c chip=0x43831002 rev=0x00 hdr=0x00 vendor = 'ATI Technologies Inc. / Advanced Micro Devices, Inc.' device = 'IXP SB600 High Definition Audio Controller' class = multimedia subclass = HDA hdac0: irq 16 at device 20.2 on pci0 hdac0: HDA Driver Revision: 20100226_0142 hdac0: [ITHREAD] hdac0: hdac_get_capabilities: Invalid rirb size (0) device_attach: hdac0 attach returned 6 I understand from the manual, there should be devices /dev/pcmX and /dev/dsp, but I have neither. I'll ask in @questions. many thanks for a quick fix! anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 331 5944 Fax: +44 (0)117 929 4423
