You can do this with "mixer recsrc" If that's set incorrectly, set it with "mixer '=rec' ", example: "mixer '=rec' line1" Next thing to check is the recording level, which you can check with "mixer" and set with "mixer <% of maximum volume>" For instance: "mixer line1 80" -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
