Running OSS build 1002 on Solaris Nevada b62 x64 here.
The driver installs, attachs fine (no errors unlike that X-Fi I threw out), the VU meters in ossxmix work when playing sounds via the various devlinks, osstest doesn't make any sounds. Combed through the dmesg logs, nothing in there either. It seems like the device works but has been permamuted.
Is this a known problem?
