Howdy all, and sorry for the cross post. I have a Compaq Armada 7800 Laptop which according to the Compaq Documentation runs a ESS1879 chipset(documentation below). I have installed Alsa and Esound and alsaconf detects it as a Ess1688, I ok this and it doesnt work, I then modify /etc/modutils/alsa to point it at the correct module snd-card-es1866(alsaconf points it at snd-card-audiodrive1688) and this also doesnt work, I can only get it to work when I install it as a Sound Blaster Pro(snd-card-sb8) but then it only runs sound at 1/2 speed. ie really slowly.
The same thing also happens without Alsa just using the sb.o out of the 2.2.14 kernel Has anyone encountered this before and/or know what I should do? Debian 2.2, Kernel 2.2.14. Thanks, Aaron ----- Start Compaq Docs ----- Audio Support 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 dont 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. -----End Compaq Docs -----
