Cirrus Logic Crystal CS4281 PCI Audio compile drivers

**volkswagner** · February 4th, 2009

Hi all,

I am trying to setup a headless jukebox with Jinzora, Ubuntu Server 8.04.2, LAMP, MPD all via an old Toshiba Laptop model 1735. I want the sound directed to the laptop sound card.

Code:

lspci -v
00:08.0 Multimedia audio controller: Cirrus Logic Crystal CS4281 PCI Audio (rev 01)
        Subsystem: Toshiba America Info Systems Unknown device ff00
        Flags: bus master, medium devsel, latency 64, IRQ 5
        Memory at fc010000 (32-bit, non-prefetchable) [size=4K]
        Memory at fc000000 (32-bit, non-prefetchable) [size=64K]
        Capabilities: <access denied>

Code:

dan@Jukebox:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: CS4281 [Cirrus Logic CS4281], device 0: CS4281 [CS4281]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
dan@Jukebox:~$ aplay -L
default:CARD=CS4281
    Cirrus Logic CS4281, CS4281
    Default Audio Device
null
    Discard all samples (playback) or generate zero samples (capture)

Following the comprehensive sound guide I have landed at compile drivers. I tried with "Using-Alsa-Source" with no joy. Modprobe still resulted in no such module.

I am stuck on the compilation from source. I have attached the output of

Code:

sudo ./configure  --with-kernel=/usr/src/linux-headers-$(uname -r) --with-cards=cs4281 --with-oss=yes

When checking dmesg I still see the same two items as prior to doing any changes.

Code:

[  917.458568] input: PC Speaker as /devices/platform/pcspkr/input/input2
[  926.793601] gameport: CS4281 Gameport is pci0000:00:08.0/gameport0, speed 2294kHz

Does this mean that the card is not detected as an output device?

Any suggestions?

SideNote: Why is the UbuntuForum Upload of text files limited to ~19Kb? A 21KB files creates a 152KB file.

I guess I need to research pastebin?
