hdac0: HDA Driver Revision: 20100226_0142
hdac0: Lazy allocation of 0x4000 bytes rid 0x10 type 3 at 0xb7fb0000
hdac0: [MPSAFE]
hdac0: [ITHREAD]
hdac0: hdac_get_capabilities: Invalid corb size (0)
hdac0: Resetting corb size to 256
hdac0: hdac_get_capabilities: Invalid rirb size (0)
hdac0: Resetting rirb size to 256
hdac0: Caps: OSS 1, ISS 0, BSS 0, NSDO 1, CORB 256, RIRB 256
