I loaded Mandrake 9.0 on an Armade 7800. All went well but no sound. I'm a real J.V. when it comes to linux, can someone walk with me on this?
Hey I like Nuxone!

have you checked compaq's how to install linux on an armada 7800?

it suggests:
Armada 7400 and 7800 uses the ESS1879 sound chip. Both RedHat Linux 5.2 and SuSE6.0 include a driver, which will allow basic sound support. This driver currently supports basic audio functionality under Linux; therefore the extra features of the ESS1879 are not available. For example, older Linux kernels included support only for the ESS688/1688, which do not have full duplex, integrated 3D-audio, hardware volume control, or a DSP port. Newer kernels include support for the ESS1878, which differs from the ESS1879 in that the 1878 don’t have integrated 3D-audio. Also, the Armada notebooks include hardware volume control handled by the system firmware. This volume control works under any OS but audio drivers must be specially modified to provide feedback to application programs that the volume has been adjusted. For example, adjusting the volume using the hardware control will not be reflected in the status of any audio mixer program. This is limitation also exists in Win* unless the Compaq specific ESS driver is used. The hardware resources used by the ESS chip can be read or changed using BIOS setup. The defaults are ”base I/O= 0x220, IRQ= 5, DMA= 1, MPU401 I/O= 0x330”. The kernel module sound driver RedHat uses is based on an older, free Open Sound System (OSS) driver. SuSE comes without sound support compiled in the kernel; instead SuSE provides two versions of the commercial OSS driver. The commercial OSS driver is available from www.4front-tech.com. In addition, ALSA, Advanced Linux Sound Architecture is available at www.alsa-project.org.
also, there are some good hints at linux on laptops regarding the sound configuration. see

Some people have told me that they've had problem getting sound to work. I've had no problems, I listen to MP3:s all the time. This
is my /etc/conf.modules:
alias sound sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1 dma16=0 mpu_io=0x330
