>Number: 23618 >Category: ports >Synopsis: Updates for newpcm duplex probing and AC97-like mixers. >Confidential: no >Severity: non-critical >Priority: low >Responsible: freebsd-ports >State: open >Quarter: >Keywords: >Date-Required: >Class: change-request >Submitter-Id: current-users >Arrival-Date: Mon Dec 18 10:50:01 PST 2000 >Closed-Date: >Last-Modified: >Originator: Orion Hodson >Release: FreeBSD 4.2-RELEASE i386 >Organization: >Environment: Machine running newpcm. >Description: The existing code detects full-duplex cards as half-duplex under newpcm. It also assumes SB-style mixer input, most new cards are AC97 style. >How-To-Repeat: >Fix: Patch enclosed that updates full duplex probing to work properly with newpcm and adds RECLEV to input gain fn for AC97 style mixers.
