Hi,
I'm trying to get good sound performance from the on motherboard ess1869 chip
in my sis5598 system. The standard kernel sb driver works, but using
mpg123 distortion and skipping is really cronic whenever there is other
activity on the box. I originally had a pentium 100 in the machine, and I put
a pentium 200 in, and the problems seemed to get worse. A Sound Blaster 16
card doesn't suffer from these problems so badly, and turning off dma on the
ide controller eliminates them completely.
I'm trying to get the alsa drivers to work, I'm hopeing that they will provide
better performance. However I can't get the module to install:
mpfree:/etc# isapnp /etc/isapnp.conf
Board 1 has Identity d7 ff ff ff ff 03 00 73 16: ESS0003 Serial No -1
[checksum d7]
ESS0003/-1[1]{ESS ES1869 Plug and Play AudioDrive}: Ports 0x240 0x388 0x300;
IRQ7 DMA0 DMA3 --- Enabled OK
ESS0003/-1[2]{ESS ES1869 Plug and Play AudioDrive}: Port 0x200; --- Enabled OK
I get this in the syslog (dates snipped for clarity)
kernel: snd: [0x240] ESS1869 chip found
kernel: snd: requested ports 0x0-0x7 busy
kernel: snd: ports (0x0-0x7) for ES18xx - CTRL are already used
kernel: snd: MAGIC==0x0: es18xx.c: 1115 [snd_es18xx_free]
kernel: snd: ESS AudioDrive ES18xx soundcard #1 not found at 0x240 or device
busy
kernel: snd: ESS AudioDrive ES18xx soundcard #2 not found or device busy
What is going on here? I'm guessing that the "requested ports 0x0-0x7 busy"
line is relative to the base address? If they aren't then it's obviously
conflicting with dma1:
mpfree:~# cat /proc/ioports
