Red Hat Bugzilla – Bug 8087
Wrong sound chip found on Dell Latitude CPi (PII 300MHz)
Last modified: 2014-03-16 22:11:49 EDT
When I run sndconfig on my Dell Latitude CPi laptop, sndconfig allowed me to choose the Crystal CS423x sound chip, which is what the laptop runs. The sound tests run by sndconfig appear to work - I can hear the wav and midi sounds. However, when running any other sound program such as play or XMMS, the sound comes out sounding very slow, like it's playing at the wrong sample rate. The fix for this was very simple. I checked /etc/conf.modules and found the sound card was set to a CS 4232. The spec sheet at http://support.dell.com shows I have a 4237. Wherever I found a 4232 in /etc/conf.modules, I changed that to 4237. Now my Shoutcast streams play perfectly. :)
That really shouldn't have worked, as there is no cs4237 module for it to load. What does your working /etc/conf.modules look like?
> cat /etc/conf.modules alias eth0 3c59x alias sound cs4237 pre-install sound /sbin/insmod sound dmabuf=1 alias midi opl3 options opl3 io=0x388 options cs4237 io=0x530 irq=5 dma=0 dma2=0 mpuio=0x330 mpuirq=5
This works for you? What does 'cat /dev/sndstat' and 'lsmod' say?
This does work me. I honestly didn't expect it to, but it does. I've been taught to troubleshoot using the most obvious tactics first, and changing /etc/conf.modules like I did was as obvious as I could get. /dev/sndstat --- [root@phatdaddy /root]# cat /dev/sndstat OSS/Free:3.8s2++-971130 Load type: Driver loaded as a module Kernel: Linux phatdaddy.corp.digex.com 2.2.12-20 #1 Mon Sep 27 10:40:35 EDT 1999 i686 Config options: 0 Installed drivers: Card config: Audio devices: 0: Crystal audio controller (CS4236) Synth devices: 0: Yamaha OPL3 Midi devices: Timers: 0: System clock 1: Crystal audio controller (CS4236) Mixers: 0: Crystal audio controller (CS4236) lsmod --- [root@phatdaddy /root]# lsmod Module Size Used by opl3 11208 0 cs4232 2440 0 uart401 5968 0 [cs4232] ds 5740 2 i82365 22640 2 pcmcia_core 39912 0 [ds i82365] 3c59x 19112 1 (autoclean) ad1848 15920 0 [cs4232] sound 57240 0 [opl3 cs4232 uart401 ad1848] soundcore 2372 5 [sound] soundlow 300 0 [sound]
That's the weird thing though; with those entries in /etc/conf.modules, the cs4232 module should never have been loaded in the first place. I'm at a loss to explain how this works for you, as it shouldn't. ;) A couple of things you might want to look at: The setting of 'dma=0 dma2=0' is somewhat odd ; normal is 'dma=1 dma2=0'. You might also want to try changing /etc/pcmcia/config.opts from: include port=0x100-0x4ff to include port=0x100-0x1ff
I can try what you suggest. I see what you did for bug #7412 and perhaps this might yield interesting results. I still do get some "popping" noises for some sounds, especially Enlightenment and Gnome efffects so some tweaking is to my advantage if I can be rid of those last few problems.
There are known problems with the cs4232 driver causing 'popping' noises; so far there isn't a fix.
