>Description:
    Audio init fails on a hdaudio device that does not support recording,
    such as HDMI output on ATI Radeon. Relevant dmesg lines are:

hdaudio0: interrupting at ioapic0 pin 19
hdafg0 at hdaudio0 vendor 0x1002 product 0xAA01 nid 0x01 (firmware 
configuration)
audio0 at hdafg0: full duplex, independent
audio: could not allocate record buffer
>How-To-Repeat:
    Boot hdaudio kernel on system with output only hdaudio, and see it fail.
>Fix:
    Don't try and fail to init recording on device that does not support
    recording?

>Unformatted:
     NetBSD 5.99.16
