lost sound after kernel reconfig


I'm a linux newbie. I just installed Slack 9.1 on my laptop. I noticed that the battery meter wasn't working in KDE, so I decided to make sure the APM option was selected in the kernel. I selected APM and ACPI (I think that was my first mistake). After recompiling the kernel using a small how to post, I noticed that I lost my sound, and APM still doesn't work. KDE Klaptop says there is no APM driver installed... Can anyone help me here?

Thanks in advance,
Ryan

What version of the Linux kernel are you compiling? What version were you running before?

It is possible that you just simply forgot to select the sound drivers for your soundcard when you configured your kernel, have you checked that? have you tried modprobe'ing the driver? Does your driver appear when you do lsmod? Are you using OSS or ALSA for sound?

To activate ACPI you also need to type acpi=on as a parameter to the kernel in your lilo.conf.

I'm not sure why your APM isn't working.

Good luck,
Mark.

I was compiling 2.4.22. My old version was the same.

I haven't tried modprobing the driver, only because my understanding of linux isn't that deep yet. There was a sound entry when I ran lsmod. Sound was previously working on ALSA, so naturally that's what I'm trying to use.

I will try acpi=on in lilo.conf. Does ACPI do the same job as APM, e.g. will I get a battery display under KDE?

I read in another post that APM and ACPI should not be used together. Is that accurate?

Thanks,
Ryan

You need more than just a sound module, you need a specific driver the the sound card you have.

Post the output of the following two commands:
Code:
$ /sbin/lsmod
$ /sbin/lspci
Also make sure that your that your sound is not muted in alsamixer.
