I brought this up on the #bsddev channel on EFnet, but nobody picked it up so I'm re-posting it here. I have been messing around trying to get the snd_hda driver to work 100% on my ThinkPad. There are a lot of HDA chips out there, and it turns out laptop manufacturers are real "cowboy" about wiring them up - pins x, y, z on one machine may not have the same function as pins x, y, z on another machine. To make matters worse, these quirks are never documented. However, Linux (and Windows) "just work" on these platforms - while FreeBSD (at least on my X230) requires manually experimenting with the snd_hda driver's configuration via device.hints. I am not sure exactly how Linux/Windows handle this - perhaps they do some kind of probing, or perhaps they ship with a long list of known quirks. My question is: is there some technical reason this has not been implemented in FreeBSD, or is it simply something waiting to be implemented? Is there any way I can help out? - BW _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to "[email protected]"
