34 .Nd Creative SoundBlaster Live! and Audigy sound cards device driver
36 To compile this driver into the kernel, place the following lines in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
40 .Cd "device snd_emu10kx"
42 For additional options:
43 .Cd "options EMU10KX_MULTICHANNEL"
44 .Cd "options EMU10KX_DEBUG"
47 Alternatively, to load the driver as a module at boot time, place the
50 .Bd -literal -offset indent
51 snd_emu10kx_load="YES"
56 bridge driver allows the generic audio driver
58 to attach to the Creative sound cards based on EMU10K1, CA0100, CA0101, CA0102
63 sound cards have a PCM part, which is accessible through one to five
66 .Sx MULTICHANNEL PLAYBACK
67 for details), and MPU401-compatible MIDI I/O controller, which is accessible
68 through the midi device.
69 Wave table synthesizer is not supported.
73 driver supports the following sound cards:
77 Creative Sound Blaster Live!\& (EMU10K1 Chipset).
78 Both PCM and MIDI interfaces are available.
80 Creative Sound Blaster Audigy (CA0100 and CA0101 Chipset).
81 PCM and two MIDI interfaces available.
83 Creative Sound Blaster Audigy 2 and Creative Sound Blaster Audigy 4 (CA0102
85 PCM support is limited to 48kHz/16 bit stereo (192kHz/24 bit part
86 of this chipset is not supported).
88 Creative Sound Blaster Audigy 2 Value (CA0108 Chipset).
89 PCM support is limited
90 to 48kHz/16 bit stereo (192kHz/24 bit part of this chipset is not supported).
91 There is no MIDI support for this card.
98 support the following sound cards (although they are named
99 similar to some supported ones):
103 Creative Sound Blaster Live!\& 24-Bit, identified by
106 .Qq Li "emu10k1x Soundblaster Live! 5.1" .
108 Creative Sound Blaster Audigy LS / ES, identified by
111 .Qq Li "CA0106-DAT Audigy LS" .
113 All other cards with -DAT chipsets.
115 .Sh MULTICHANNEL PLAYBACK
116 It is possible to build this driver with multichannel playback capabilities.
118 .Dv EMU10KX_MULTICHANNEL
119 option in your kernel configuration (or
120 build it as a module) you will get up to five DSP devices, one for each sound
124 output can play and record sound from external
125 sources (like line or S/PDIF inputs).
126 .Sh OSS MIXER CONTROLS
127 These are controls available through the standard OSS programming interface.
132 On EMU10K1-based cards the OSS mixer directly controls the AC97 codec on card.
133 On newer cards the OSS mixer controls some parameters of the AC97 codec and
134 some DSP-based mixer controls.
137 mixer control is overall sound volume.
139 mixer control is PCM playback volume.
140 It controls only front output
141 volume in multichannel mode and all output volume in single channel mode.
143 mixer control acts very different on EMU10K1 and other cards.
144 On EMU10K1 cards it controls the AC97 codec recording level.
146 it controls the amount of AC97 "stereo mix" entering the DSP.
147 AC97 recording level and AC97 recording source are fixed
148 on CA0100, CA0101, CA0102 and CA0108 cards.
149 AC97 recording level are always set to
150 maximum and recording source is always
151 .Dq Li "stereo mix" .
154 Other OSS mixer controls do not work.
155 .Sh PRIVATE DEVICE CONTROLS
156 You can control most of EMU10Kx operation and configuration parameters through
157 .Va dev.emu10kx. Ns Aq Ar X

206 8kHz/8bit/mono recording does not work.
207 8kHz recording was removed from the driver capabilities.
209 The driver does not detect lost S/PDIF signal and produces noise when S/PDIF
210 is not connected and S/PDIF volume is not zero.
212 The PCM driver cannot detect the presence of Live!Drive or AudigyDrive
214 and tries to use them (and list their connectors in the mixer).
216 The MIDI driver cannot detect the presence of Live!Drive or AudigyDrive
217 breakout boxes and tries to enable the IR receiver on them anyway.
