But really some (or probably most... or jast all) CS4232 based cards uses 2 and 3 registers for 'line' and 18, 19 for 'synth'. Also, CS4235 have "master out" AKA 'vol' device at 27 and 29 registers. >How-To-Repeat: Plug some audio source to "line in" of sound card. try "mixer line <level>" and "mixer synth <level>" to change volume. >Fix: 'mix_devices' definition should contains following lines for CS4232 MIX_ENT(SOUND_MIXER_SYNTH, 18, 1, 0, 5, 19, 1, 0, 5), MIX_ENT(SOUND_MIXER_LINE, 2, 1, 0, 5, 3, 1, 0, 5), and following one for CS4235 MIX_ENT(SOUND_MIXER_VOLUME, 27, 1, 0, 4, 29, 1, 0, 4), >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
