8 tristate "PC-Speaker support (READ HELP!)"
9 depends on PCSPKR_PLATFORM && X86_PC && HIGH_RES_TIMERS
11 depends on EXPERIMENTAL
15 If you don't have a sound card in your computer, you can include a
16 driver for the PC speaker which allows it to act like a primitive
18 This driver also replaces the pcspkr driver for beeps.
20 You can compile this as a module which will be called snd-pcsp.
22 WARNING: if you already have a soundcard, enabling this
23 driver may lead to a problem. Namely, it may get loaded
24 before the other sound driver of yours, making the
25 pc-speaker a default sound device. Which is likely not
26 what you want. To make this driver play nicely with other
27 sound driver, you can add this into your /etc/modprobe.conf:
28 options snd-pcsp index=2
30 You don't need this driver if you only want your pc-speaker to beep.
31 You don't need this driver if you have a tablet piezo beeper
32 in your PC instead of the real speaker.
34 Say N if you have a sound card.
36 Say Y only if you really know what you do.
38 config SND_MPU401_UART
63 tristate "Dummy (/dev/null) soundcard"
67 Say Y here to include the dummy driver. This driver does
68 nothing, but emulates various mixer controls and PCM devices.
70 You don't need this unless you're testing the hardware support
71 of programs using the ALSA API.
73 To compile this driver as a module, choose M here: the module
74 will be called snd-dummy.
77 tristate "Virtual MIDI soundcard"
78 depends on SND_SEQUENCER
82 Say Y here to include the virtual MIDI driver. This driver
83 allows to connect applications using raw MIDI devices to
86 If you don't know what MIDI is, say N here.
88 To compile this driver as a module, choose M here: the module
89 will be called snd-virmidi.
92 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"
105 depends on SND && PARPORT
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"
121 To include support for MIDI serial port interfaces, say Y here
122 and read <file:Documentation/sound/alsa/serial-u16550.txt>.
123 This driver works with serial UARTs 16550 and better.
125 This driver accesses the serial port hardware directly, so
126 make sure that the standard serial driver isn't used or
127 deactivated with setserial before loading this driver.
129 To compile this driver as a module, choose M here: the module
130 will be called snd-serial-u16550.
133 tristate "Generic MPU-401 UART driver"
135 select SND_MPU401_UART
137 Say Y here to include support for MIDI ports compatible with
138 the Roland MPU-401 interface in UART mode.
140 To compile this driver as a module, choose M here: the module
141 will be called snd-mpu401.
143 config SND_PORTMAN2X4
144 tristate "Portman 2x4 driver"
145 depends on SND && PARPORT
148 Say Y here to include support for Midiman Portman 2x4 parallel
151 To compile this driver as a module, choose M here: the module
152 will be called snd-portman2x4.
154 config SND_ML403_AC97CR
155 tristate "Xilinx ML403 AC97 Controller Reference"
156 depends on SND && XILINX_VIRTEX
157 select SND_AC97_CODEC
159 Say Y here to include support for the
160 opb_ac97_controller_ref_v1_00_a ip core found in Xilinx' ML403
163 To compile this driver as a module, choose M here: the module
164 will be called snd-ml403_ac97cr.
