27 bool "Generic sound devices"
30 Support for generic sound devices.
35 tristate "PC-Speaker support (READ HELP!)"
36 depends on PCSPKR_PLATFORM && X86 && HIGH_RES_TIMERS
38 depends on EXPERIMENTAL
41 If you don't have a sound card in your computer, you can include a
42 driver for the PC speaker which allows it to act like a primitive
44 This driver also replaces the pcspkr driver for beeps.
46 You can compile this as a module which will be called snd-pcsp.
48 WARNING: if you already have a soundcard, enabling this
49 driver may lead to a problem. Namely, it may get loaded
50 before the other sound driver of yours, making the
51 pc-speaker a default sound device. Which is likely not
52 what you want. To make this driver play nicely with other
53 sound driver, you can add this into your /etc/modprobe.conf:
54 options snd-pcsp index=2
56 You don't need this driver if you only want your pc-speaker to beep.
57 You don't need this driver if you have a tablet piezo beeper
58 in your PC instead of the real speaker.
60 Say N if you have a sound card.
62 Say Y only if you really know what you do.
65 tristate "Dummy (/dev/null) soundcard"
68 Say Y here to include the dummy driver. This driver does
69 nothing, but emulates various mixer controls and PCM devices.
71 You don't need this unless you're testing the hardware support
72 of programs using the ALSA API.
74 To compile this driver as a module, choose M here: the module
75 will be called snd-dummy.
78 tristate "Virtual MIDI soundcard"
79 depends on SND_SEQUENCER
83 Say Y here to include the virtual MIDI driver. This driver
84 allows to connect applications using raw MIDI devices to
87 If you don't know what MIDI is, say N here.
89 To compile this driver as a module, choose M here: the module
90 will be called snd-virmidi.
93 tristate "MOTU MidiTimePiece AV multiport MIDI"
96 To use a MOTU MidiTimePiece AV multiport MIDI adapter
97 connected to the parallel port, say Y here and make sure that
98 the standard parallel port driver isn't used for the port.
100 To compile this driver as a module, choose M here: the module
101 will be called snd-mtpav.
104 tristate "ESI Miditerminal 4140 driver"
108 The ESI Miditerminal 4140 is a 4 In 4 Out MIDI Interface with
109 additional SMPTE Timecode capabilities for the parallel port.
111 Say 'Y' to include support for this device.
113 To compile this driver as a module, chose 'M' here: the module
114 will be called snd-mts64.
116 config SND_SERIAL_U16550
117 tristate "UART16550 serial MIDI driver"
120 To include support for MIDI serial port interfaces, say Y here
121 and read <file:Documentation/sound/alsa/serial-u16550.txt>.
122 This driver works with serial UARTs 16550 and better.
124 This driver accesses the serial port hardware directly, so
125 make sure that the standard serial driver isn't used or
126 deactivated with setserial before loading this driver.
128 To compile this driver as a module, choose M here: the module
129 will be called snd-serial-u16550.
132 tristate "Generic MPU-401 UART driver"
133 select SND_MPU401_UART
135 Say Y here to include support for MIDI ports compatible with
136 the Roland MPU-401 interface in UART mode.
138 To compile this driver as a module, choose M here: the module
139 will be called snd-mpu401.
141 config SND_PORTMAN2X4
142 tristate "Portman 2x4 driver"
146 Say Y here to include support for Midiman Portman 2x4 parallel
149 To compile this driver as a module, choose M here: the module
150 will be called snd-portman2x4.
152 config SND_ML403_AC97CR
153 tristate "Xilinx ML403 AC97 Controller Reference"
154 depends on XILINX_VIRTEX
155 select SND_AC97_CODEC
157 Say Y here to include support for the
158 opb_ac97_controller_ref_v1_00_a ip core found in Xilinx' ML403
161 To compile this driver as a module, choose M here: the module
162 will be called snd-ml403_ac97cr.
164 config SND_AC97_POWER_SAVE
165 bool "AC97 Power-Saving Mode"
166 depends on SND_AC97_CODEC
169 Say Y here to enable the aggressive power-saving support of
170 AC97 codecs. In this mode, the power-mode is dynamically
171 controlled at each open/close.
173 The mode is activated by passing power_save=1 option to
174 snd-ac97-codec driver. You can toggle it dynamically over
177 config SND_AC97_POWER_SAVE_DEFAULT
178 int "Default time-out for AC97 power-save mode"
179 depends on SND_AC97_POWER_SAVE
182 The default time-out value in seconds for AC97 automatic
183 power-save mode. 0 means to disable the power-save mode.
