I connected my sound source to the line input. I set all mixers to 0 but the only I really needed to get it to work. So you can use only those and get a clear sound input. $ mixer Recording source: line1 Mixer vol is currently set to 64:64 Mixer pcm is currently set to 81:81 Mixer speaker is currently set to 0:0 Mixer line is currently set to 100:100 Mixer mic is currently set to 0:0 Mixer cd is currently set to 0:0 Mixer rec is currently set to 100:100 Mixer ogain is currently set to 0:0 Mixer line1 is currently set to 0:0 Mixer phin is currently set to 0:0 Mixer phout is currently set to 0:0 Mixer video is currently set to 0:0 Just the same with emuctrl. I am using the minimum options required. $ emuctrl list Id Description Vol RecVol FX (PCM) buses fx0 DSP FX BUS 0 83:83 (0:0) DSP Inputs in0 AC97 Codec 0:0 (100:100) in1 CD S/PDIF 0:0 (0:0) in2 Optical S/PDIF 0:0 (0:0) in3 0x06 0:0 (0:0) in4 Line-In (2) 0:0 (0:0) in5 Coaxial S/PDIF 0:0 (0:0) in6 AUX2 0:0 (0:0) in7 0x0E 0:0 (0:0) DSP Outputs out0 DIGITAL: Front 0:0 out1 DIGITAL: Center 0 out2 DIGITAL: Subwoofer 0 out3 Headphones 100:100 out4 DIGITAL: Rear 0:0 out5 Front 100:100 out6 Center 100 out7 Subwoofer 100 out8 Side 0:0 out9 Rear 100:100 out10 AC97 ?? 0:0 out11 0x12 0:0 out12 0x14 0:0 out13 A/D converter (REC) 100:100 out14 0x18 0:0 out15 0x1A 0:0 out16 0x1C 0:0 out17 0x1E 0:0 > Does it produce better sound than recoding from AC97 mic? Yes, line input produces excellent quality. It would be nice if you added those figures above to the FAQ. :) Let me know if you want me to test anything. I would really like to be of assistance. Thanks a lot for everybody's help. Just one question remains. My video input is /dev/bktr0 alas my audio input is /dev/audio0.1. How do I get mplayer to record both audio and video at the same time from different sources? mplayer(1) man page mentions a "adevice=3Dfile" option but mplayer complains it does not exist. This works without audio just fine $ mplayer -tv driver=3Dbsdbt848:noaudio:width=3D640:height=3D480:input=3D0:= norm=3Dntsc tv:// But this doesn't. $ mplayer -tv driver=3Dbsdbt848:adevice=3D/dev/audio0.1:width=3D640:height= =3D480:input=3D0:norm=3Dntsc tv:// MPlayer 1.0pre7-3.4.2 (C) 2000-2005 MPlayer Team CPU: Advanced Micro Devices Athlon MP/XP/XP-M Barton (Family: 6, Stepping: = 0) Detected cache-line size is 64 bytes CPUflags: MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0 Compiled with runtime CPU detection - WARNING - this is not optimal! To get best performance, recompile MPlayer with --disable-runtime-cpudetect= ion. Option tv: Unknown suboption adevice In case you're wondering if audio0.1 works $ ls -l /dev/audio0.1 crw-rw-rw- 1 root wheel 30, 0x00010004 Apr 18 01:24 /dev/audio0.1 Using wavrec works just fine so I know the audio input device is sound. $ wavrec -d /dev/audio0.1 test.wav Any help is appreciated. Oh, in case you guys want to use my sample of mplayer 1.0pre7, it can be found at http://people.FreeBSD.org/~lioux/mplayer.tgz It is not a final version but it is working just fine for me.
