Cirrus Logic CS4281 for Linux driver download free

Provides Linux support for CS4281 To install the driver,­ ensure that the environmental requirements are met (See Frequently Asked Questions text file,­ question 3.­) and complete the following steps: 1.­ Download the gzip file.­ 2.­ Create a directory to extract the file (example: mkdir /­cs4281).­ 3.­ Change directory to the /­cs4281 directory to extract the files.­ 4.­ Copy the downloaded gzip file into the /­cs4281 directory.­ 5.­ Perform a "gunzip [downloaded filename]" to extract the gzip file into a tar format file.­ 6.­ Perform a tar -x < [downloaded filename] to extract the files from the tar archive.­ 7.­ Change directory to the /­usr/­src/­[linux] directory.­ 8.­ Verify that the driver is enabled as a module (M) (using "make xconfig",­ "make menuconfig",­ or "make config" in the Sound category).­ 9.­ Make a backup of all of the cs4281* files in the [cs4281] source directory.­ /­usr/­src/­[linux]/­drivers/­sound/­[cs4281](cs4281*.­c,­ cs4281*.­h).­ 10.­ Copy all of the files from the newly created /­cs4281 directory into the /­usr/­src/­[linux]/­drivers/­sound/­[cs4281] directory overwriting the older files.­ 11.­ Make a new CS4281 driver module by performing a "make dep" and then a "make modules_­install" from the /­usr/­src/­[linux] directory.­ 12.­ Make a new CS4281 driver module by performing a "make dep",­ "make modules",­ and then a "make modules_­install" from the /­usr/­src/­[linux] directory.­ The new CS4281 driver will be automatically copied into the /­lib/­modules/­[linux] directory tree.­ 13.­ Edit the /­etc/­modules.­conf file (or /­etc/­conf.­modules on older versions of linux),­ and make sure that "sndconfig" has placed either the line "alias sound-slot-0 cs4281" or "alias sound cs4281" in that file.­ 14.­ Reboot the system and the new driver will load automatically.­ Notes: See the Frequently Asked Question text file for additional information including installation environmental requirements.­
