kernel upgrade has stopped sound working

pwc101 · 08-24-2006, 01:19 PM

I followed this guide to upgrade my kernel from the stock 2.4 slackware install kernel to the latest one from -current (2.6.16.27).

http://www.linuxquestions.org/linux/...Install_disc_2

I've got no problems booting, everything works fine except I have no more sound. It's correctly identifying my soundcard if I run lspci:

Code:

00:00.0 Host bridge: VIA Technologies, Inc. VT8366/A/7 [Apollo KT266/A/333]
00:01.0 PCI bridge: VIA Technologies, Inc. VT8366/A/7 [Apollo KT266/A/333 AGP]
00:06.0 Ethernet controller: Intel Corporation 82557/8/9 [Ethernet Pro 100] (rev 08)
00:08.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 61)
00:08.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 61)
00:08.2 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 63)
00:09.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07)
00:09.1 Input device controller: Creative Labs SB Live! MIDI/Game Port (rev 07)
00:11.0 ISA bridge: VIA Technologies, Inc. VT8233 PCI to ISA Bridge
00:11.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)
00:11.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 18)
01:00.0 VGA compatible controller: nVidia Corporation NV11 [GeForce2 MX/MX 400] (rev a1)

It seems to suggest that it's correctly identified the card, and it mention the emu10k1 module which is what I used when using the 2.4 kernel.

However, whereas when I had the 2.4 kernel and I ran alsaconf, it detected the card and loaded the correct module, but now I get this from alsaconf:

Code:

No Supported PnP or PCI card found.

Would you like to probe legacy ISA sound cards/chips?

If I hit yes, I get

Code:

No legacy drivers are available

This is my /etc/modules.conf:

Code:

# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.9a ---
alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-emu10k1
alias sound-slot-0 snd-emu10k1
# --- END: Generated by ALSACONF, do not edit. ---

.

Anyone got any ideas how I fix this?

Thanks.

I'm in the middle of double checking my first kernal compile (2.6 also) and it seems like I remember seeing an option to compile alsa support into the kernel... Did you happen to do that?

I could be wrong since I'm feeling my way through this myself, but I'm certain I saw that option when configureing my kernel.

good luck!

Did you add support for you card in your new kernel. What's the output:

Code:

cat /usr/src/linux/.config|grep SND_EMU

If you have compile it as a module try:

Code:

modprobe snd-emu10k1

ah, sorry, I should have been more specifi: I'm afraid I'm not compiling my own kernel, but rather using one of the precompiled one that's available as a .tgz, and I just installed that as you would any .tgz and edited my lilo config and ran mkinitrd. I got the .tgz's from here http://slackware.mirrors.tds.net/pub...nux-2.6.16.27/, and just installed those. I'm not sure what's in them, but an lsmod reveals the following:

Code:

which doesn't seem to mention the emk10k1 module.

How would I go about installing that separately, or would I need to compile my own kernel? (I plan on doing this one day anyway, but I've got to hand in my thesis next friday, so my priorities are elsewhere at the moment!)

edit: whoops, lsmod does seem to mention it, but there's still no sound!

(see, too much pressure with this damn thesis - can't even read the output from lsmod!)

simcox1 · 08-24-2006, 02:36 PM

When you upgraded the kernel, did you also install the alsa package for the new kernel?

pwc101 · 08-25-2006, 01:45 AM

simcox1, I have one word for you: legend!

something so simple

thanks folks
