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

198 The MIDI interface is based on the

207 8kHz/8bit/mono recording does not work.
208 8kHz recording was removed from the driver capabilities.
210 The driver does not detect lost S/PDIF signal and produces noise when S/PDIF
211 is not connected and S/PDIF volume is not zero.
213 The PCM driver cannot detect the presence of Live!Drive or AudigyDrive
215 and tries to use them (and list their connectors in the mixer).
217 The MIDI driver cannot detect the presence of Live!Drive or AudigyDrive
218 breakout boxes and tries to enable the IR receiver on them anyway.
