Hello,

I am running Slackware 10.0 distro with kernel 2.4.26

When I download, compile and install the latest source of alsa and after I run "alsaconf", the sound plays perfrectly. The mixer that I have access to is "Realtek ALC100/100P rev 38 [(Audio Mixer (OSS)]".

However, here is the problem. After installing alsa and everything works fine, I reboot my computer. After the reboot, the sound no longer works, the weird thing is that a new sound driver is installed and the mixer that I now have access to is "Bt87x [(Audio Mixer (OSS)]"

After some fiddling around, I figured that the problem is hotplug. On my computer I have a SiS sound card and I also have an ATI TV Wonder Ve TV Tuner. I think that when hotplug starts, it detects the audio chip that is on my TV tuner and afterwards alsa loads the audio drivers for the TV tuner instead.

I changed my init scripts so that hotplug does not get invoked anymore on system startup. Alsa works correctly, the correct sound driver is loaded and I can get sound again. However, my ethernet card is no longer detected. I need hotplug to run to get my ethernet to work.

I tried to change the hotplug scripts a bit (the file pci.rc) so that it only loads my ethernet card driver and no other drivers but I still could not get alsa to load the proper sound driver. Could someone please give me some advice ?

Below I have an output of my pci devices from lspci

Check out the pci.ids file @ /usr/share/misc/pci.ids

You could comment out the brooktree lines... but that would probably render your tv card useless...but perhaps you could scan for it later, or manually install it after the other card is "installed.".

When Alsa sets up it defines each card as card0 card1 in

/proc/asound/

Chances are your card has been configured by ALSA but the rest of your system is assuming that the 1st card found ie card0 is the card you want to use for sound...

The gentleman below may be able to help you as he changed his AdvancedCD application so it would find my nforce audio instead of my btaudio card.. but again I think it just removes the TV card altogether

Add lines to /etc/modules.conf that includes your sound, ethernet, video graphics, video capture, etc. Specify the index or card option for certain modules. If you want your on-board sound to be the first sound device specify index=0. If you want BT878 audio be the second device, specify index=1. You do not have to mess around with hotplug.
