Red Hat Bugzilla – Bug 124630
CMIPCI on board sound card Configed no sound
Last modified: 2015-01-04 17:06:35 EST
Description of problem: Really simple no sound does not do a thing bar load driver into memory Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1. Have CMIPCI motherboard/sound card 2. auto detect sound card 3. No test sound/No sound Actual results: No sound Expected results: Sound Additional info: The fix is really simple add the option line to the modules file. options snd-cmipci id="first" mpu_port=0x300 The dam driver does not have any default setting give it no setting it loads and does nothing more than what sending a sound file to a NULL will. Also Please give a advanced button with the means of entering a manual options line if required so that new users don't have to be manually editing it in for other cards. Basicly it is a verry annoying Opps as a lot of on board sound users this driver.
Fix did not work for me. But in my modprobe.conf the module was spelled cmpci, as was the name of the old oss driver name. Changing this line to alias sound-slot-0 snd-cmipci and the corresponding line in /etc/sysconfig/hwconf to driver: snd-cmipci worked for me. Perhaps this mess had something to do with the upgrade process from FC1 to FC2.A (redhat-magazine). I did not test the fix on a clean FC2 installation.
Burkhard: If the /etc/modprobe.conf read "alias sound-slot-0 cmpci", and not "alias sound-slot-0 snd-cmipci", that would a relic of your FC1 installation, you would have had to change that by hand. oiaohm: I'll reassign this bug to kudzu, which should be able to detect and configure your card properly. Is the card PCI or ISA? If it is ISA, could you attach the output of isapnp to this issue? If it isn't, then the bug should be reassigned to the kernel, as the users shouldn't have to do more than selecting the driver for the card to work.
The bad rename on upgrade is fixed in current hwdata packages, FWIW.
My problem is that I have had 2 different motherboards onboard that are not mine both gave the same error ie I missed geting the file while I was setting them up if I get a third attempt. That is the reson for that being missing. Sorry Burkhard these were clean installs alias sound-slot-0 was right with snd-cmipci problem was that the driver was not coming up with a default as was mentioned alsa site ie options snd-cmipci id="first" mpu_port=0x300 added to the modules file and is required. And it is also the reason why I ask for a way to add a option line in case of strange errors so can simply over ride if needed. Basicly my problem has nothing to do with Burkhards problem.
I am experiencing the same issue on my fresh install of FC2 at home. I have a CMI8738 4 channel PCI soundcard. This worked well in FC1. I tried adding the: options snd-cmipci id="first" mpu_port=0x300 and rebooting but still had no sound. I will update this report once I get the workaround or fix.
I when over alsa-project.org again I guess either I stuffed up or the onboards I was working with was strange note I had the model number when I got the info this is a case I work on something forget to get all the info and have a problem latter 2. This line is the fix for the cmi8738 and Looks like most others is. options snd-cmipci id="first" enable_midi="1" I going to www.alsa-project.org when I have problems in this section sorry about the mistack. I the fault is right somewhere the notes file got the patch mixed up.
Created attachment 102347 [details] lspci -vv for the CMI 8738 soundcard
its okay oiaohm, i was able to find the workarounds for this issue: METHOD 1: 1) Login as root and open a terminal from system tools. Issue the following: alsactl store 2) Edit the following file: /etc/asound.state and change the following controls to false: "Exchange DAC" and "IEC958 In Monitor" example: control.26 { comment.access 'read write' comment.type BOOLEAN iface MIXER name 'Exchange DAC' value false } control.32 { comment.access 'read write' comment.type BOOLEAN iface MIXER name 'IEC958 In Monitor' value false } and then save and exit the file. 3) Issue the following to apply the the new sound settings: alsactl restore 4) Enjoy your sounds!!! METHOD 2: 1) Run the "Kmix" program from "Sound and Video". 2) Check the "advanced" checkbox and it should show you a lot more options. 3) Disable the following controls: "Exchange DAC" and "IEC958 In Monitor" by clicking on the green buttons assigned to them. 4) Enjoy your sounds. NOTE: I have attached the lspci -vv for the soundcard before this comment.
If these are required by default, I'm curious why they're not set that way in the driver.
These below are not default setting control.26 { comment.access 'read write' comment.type BOOLEAN iface MIXER name 'Exchange DAC' value false } control.32 { comment.access 'read write' comment.type BOOLEAN iface MIXER name 'IEC958 In Monitor' value false } These are partical card work arounds(most likey locked to brand and/or model number). This is a work around from the 03 March 2004. I back using this Number one if card is trouble ie a one with a problem this will alown it to work or if the card works find. From the notes on alsa some card might also have chipset problems in the IEC958 lso found why the mpu_port=0x300 it is the work around in a version of Alsa ie mpu_port=0x300 equals enable_midi="1" option part >For Alsa 1.0.0rc2: to enable the MIDI port on the MD-Mate, add the >line > > options snd-cmipci mpu_port=0x300 > >to the file "/etc/modules.conf". The option "enable_midi" is no >longer supported, as it seems. This could be out of date
Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
