40    help
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
43      sound card.
44      This driver also replaces the pcspkr driver for beeps.
45
46      You can compile this as a module which will be called snd-pcsp.
47
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
55
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.
59
60      Say N if you have a sound card.
61      Say M if you don't.
62      Say Y only if you really know what you do.
63
64config SND_DUMMY
65    tristate "Dummy (/dev/null) soundcard"
66    select SND_PCM
67    help
68      Say Y here to include the dummy driver. This driver does
69      nothing, but emulates various mixer controls and PCM devices.
70
71      You don't need this unless you're testing the hardware support
72      of programs using the ALSA API.
73
74      To compile this driver as a module, choose M here: the module
75      will be called snd-dummy.

83      Say Y here to include the virtual MIDI driver. This driver
84      allows to connect applications using raw MIDI devices to
85      sequencer clients.
86
87      If you don't know what MIDI is, say N here.

109          additional SMPTE Timecode capabilities for the parallel port.
110
111      Say 'Y' to include support for this device.
112

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.
123
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.
127
128      To compile this driver as a module, choose M here: the module
