860 | ** by Alsa. | |

942 | ** Initialize the Wine Alsa sub system. | |
943 | ** The main task is to probe for and store a list of all appropriate playback | |
944 | ** and capture devices. | |
945 | ** Key control points are from the registry key: | |
946 | ** [Software\Wine\Alsa Driver] | |
947 | ** AutoScanCards Whether or not to scan all known sound cards | |
948 | ** and add them to Wine's list (default yes) | |
949 | ** AutoScanDevices Whether or not to scan all known PCM devices | |
950 | ** on each card (default no) | |
951 | ** UseDirectHW Whether or not to use the hw:X device, | |
952 | ** instead of the fancy default:X or plughw:X device. | |
953 | ** The hw:X device goes straight to the hardware | |
954 | ** without any fancy mixing or audio scaling in between. | |
955 | ** DeviceCount If present, specifies the number of hard coded | |
956 | ** Alsa devices to add to Wine's list; default 0 | |
957 | ** DevicePCMn Specifies the Alsa PCM devices to open for | |
958 | ** Device n (where n goes from 1 to DeviceCount) | |
959 | ** DeviceCTLn Specifies the Alsa control devices to open for | |
960 | ** Device n (where n goes from 1 to DeviceCount) | |
961 | ** | |
962 | ** Using AutoScanCards no, and then Devicexxx info | |
963 | ** is a way to exactly specify the devices used by Wine. | |
