- Default: 1
- For auto-loading more than one card, specify this
option together with snd-card-X aliases.
- device_mode
- - permission mask for dynamic sound device filesystem
- - This is available only when DEVFS is enabled
- - Default: 0666
- - E.g.: device_mode=0660
Module snd-pcm-oss
position_fix - Fix DMA pointer (0 = auto, 1 = none, 2 = POSBUF, 3 = FIFO size)
single_cmd - Use single immediate commands to communicate with
codecs (for debugging only)
- disable_msi - Disable Message Signaled Interrupt (MSI)
+ enable_msi - Enable Message Signaled Interrupt (MSI) (default = off)
This module supports one card and autoprobe.

omni - Omni I/O support for MidiMan M-Audio Delta44/66
- cs8427_timeout - reset timeout for the CS8427 chip (S/PDIF transciever)
+ cs8427_timeout - reset timeout for the CS8427 chip (S/PDIF transceiver)
in msec resolution, default value is 500 (0.5 sec)
This module supports multiple cards and autoprobe. Note: The consumer part
Note: on some notebooks the buffer address cannot be detected
automatically, or causes hang-up during initialization.
- In such a case, specify the buffer top address explicity via
- buffer_top option.
+ In such a case, specify the buffer top address explicitly via
+ the buffer_top option.
For example,
Sony F250: buffer_top=0x25a800
Sony F270: buffer_top=0x272800
# OSS/Free portion
alias sound-slot-0 snd-interwave
alias sound-slot-1 snd-ens1371
------ /etc/moprobe.conf
+----- /etc/modprobe.conf
In this example, the interwave card is always loaded as the first card
(index 0) and ens1371 as the second (index 1).
options of snd-pcm-oss module.
-DEVFS support
-=============
-
-The ALSA driver fully supports the devfs extension.
-You should add lines below to your devfsd.conf file:
-
-LOOKUP snd MODLOAD ACTION snd
-REGISTER ^sound/.* PERMISSIONS root.audio 660
-REGISTER ^snd/.* PERMISSIONS root.audio 660
-
-Warning: These lines assume that you have the audio group in your system.
- Otherwise replace audio word with another group name (root for
- example).
