This has been around for quite a while, but I always chalked it up to header file mismatches. On my system, the mixer(1) command doesn't have the right mapping of labels to inputs. For instance: louie@whizzo[79] $ mixer Mixer synth is currently set to 26:26 Mixer pcm is currently set to 58:58 Mixer speaker is currently set to 84:84 Mixer line is currently set to 65:65 Mixer mic is currently set to 64:64 Mixer cd is currently set to 26:26 Mixer mix is currently set to 11:11 Mixer igain is currently set to 9:9 louie@whizzo[80] $ The thing listed as "cd" isn't; to change the level of the audio coming from the CDROM drive audio connection you have to fiddle with the "synth" mixer input. At least the "pcm" mixer control corresponds to the right thing, as does the "line" mixer input. This is with a GUS PnP board: louie@whizzo[82] $ cat /dev/sndstat VoxWare Sound Driver:3.5-alpha15-970806 (Wed Aug 6 22:58:35 PDT 1997 Amancio Hasty@rah.star-gate.com) Config options: Installed drivers: Type 4: Gravis Ultrasound Card config: Gravis Ultrasound at 0x230 irq 11 drq 5,7 Audio devices: 0: GUS PNP (CS4231) (DUPLEX) 1: Gravis UltraSound (DUPLEX) Synth devices: 0: Gravis PNP (1024k) Midi devices: 0: Gravis UltraSound Midi Timers: 0: System clock 1: GUS Mixers: 0: AD1848/CS4248/CS4231 1: Gravis Ultrasound louie@whizzo[83] $ If the API could be reworked (or perhaps just augmented), it would be nice to be able to ask the driver on the system what the mapping was rather than rely on constants in the header file. I guess in a perfect world this wouldn't be a problem, but in my world, it's not doing the right thing :-) Inevitablely, the magic numbers in the header files have to be "right" to ensure compatibility with the voxware and OSS drivers.. louie
