The following reply was made to PR kern/16587; it has been noted by GNATS. From: Matthew Reimer <mreimer@vpop.net> To: freebsd-gnats-submit@FreeBSD.org, mreimer@vpop.net Cc: Subject: Re: kern/16587: Can't record with newpcm & CS4236 (AW35/Pro) Date: Wed, 23 Feb 2000 11:13:22 -0800 Partial fix: the following patch correctly configures the card for dual channel DMA. The problem was that the SDC bit (0x04) can only be set in the MCE state. So now recording doesn't hang, and data is returned, but the recorded sound doesn't sound right when played back.
