Hi,
Alan Cox stated a few weeks ago that there is support for the Crystal
soundchip CS4235 in kernel 2.1.132ac1. I have an Acer motherboard with
this chip and so decided to make the latest available kernel
linux-2.2.0-pre7.
I found no references to CS4235 and so took the closest config option
CS4232.
Unfortunately
cat /usr/lib/xemacs-20.4/etc/sounds/im_so_happy.au > /dev/audio
simply gave silence.
I would be very glad if someone out there could give me advice.
Kind regards
Gerd
Here are the details:
To avoid module trouble I made a kernel with builtin support for
CS4232. These are my defines:
CONFIG_SOUND_CS4232=y
CONFIG_CS4232_BASE=534
CONFIG_CS4232_IRQ=5
CONFIG_CS4232_DMA=0
CONFIG_CS4232_DMA2=1
CONFIG_CS4232_MPU_BASE=3a8
CONFIG_CS4232_MPU_IRQ=9
I took the values from Windows98 which is alternatively running on the
same box and working fine with the CS4235.
dmesg says the following:
Sound initialization started
<Crystal audio controller (CS4235)> at 0x534 irq 5 dma 0,1
ad1848: Interrupt test failed (IRQ5)
Sound initialization complete
cat /dev/sndstat gives me:
