sound and the OSS vs ALSA


Hey everybody. Thanks for taking the time to help me out here.

I'm running slack 10.1 on an hp ze4420us laptop... and I've actually got it almost working completely. I've got wireless internet up... which only took me about two weeks . I've also got my usb keyboard and mouse working, and I have one more thing I haven't yet gotten to work: sound.

Here's the output of lpsci -v

I looked up the multmedia audio controller, found out that it was ?trident? controlled, so enabled the OSS with the trident module in my kernel. Recompiled, and ran. Now the system beep works when I hit backspace one too many times, but whenever I load up into a windows manager to run xmms it fails to load the sound server.

I think I've learned a lot through installing slack on my laptop and my desktop, but please, I don't think I'm an expert yet . If anybody could start me off on the path to a solution I'd dearly appreciate it,

Sincerely,

James Kassemi

James, according to the Alsa sound card matrix you have a card compatible with the Alsa snd-ali5451 driver module. See if you have the driver built and installed already by typing modinfo snd-ali5451. If the module isn't found you will have to install the Alsa drivers, either from your distribution (the version needs to match your kernel version exactly) or by building it from source (this requires the headers and/or sources for your running kernel to be installed).

You can find more information here.

Compiling the kernel with the ALSA support right now... Hopefully it works. I'm going to have to reboot when it's done, but I'll post with results. Thanks for your help though.

Okay... I've compiled about four more times getting the drivers to install without an error coming from my rc.alsa script... Here's the message I get now:

Code:
Loading ALSA mixer settings:  /usr/sbin/alsactl restore
Loading OSS compatibility modules for ALSA.
But unfortunately I get the following system message from dmesg:

Code:
Advanced Linux Sound Architecture Driver Version 1.0.6 (Sun Aug 15 07:17:53 2004 UTC).
ALSA device list:
  No soundcards found.
And in case you're not familiar with the rc.alsa script in slackware 10:

Code:
#!/bin/sh
# Load the mixer settings and OSS compatibility for ALSA.
# (the Advanced Linux Sound Architecture)

# A function to load the ALSA mixer settings:
load_alsa_mixer() {
  if [ -r /etc/asound.state ]; then
    echo "Loading ALSA mixer settings:  /usr/sbin/alsactl restore"
    /usr/sbin/alsactl restore
  else
    echo "ALSA warning:  No mixer settings found in /etc/asound.state."
    echo "  Sound may be muted.  Use 'alsamixer' to unmute your sound card,"
    echo "  and then 'alsactl store' to save the default ALSA mixer settings"
    echo "  to be loaded at boot."
  fi
}

# A function to load the ALSA OSS compat modules:
load_alsa_oss_modules() {
  if ! cat /proc/modules | grep -w snd-pcm-oss 1> /dev/null 2> /dev/null ; then
    echo "Loading OSS compatibility modules for ALSA."
    modprobe snd-pcm-oss
    modprobe snd-mixer-oss
  fi
}

# If hotplug or something else has loaded the ALSA modules, then
# simply load the mixer settings and make sure the OSS compat
# modules are loaded:
if [ -d /proc/asound ]; then
  load_alsa_mixer
  load_alsa_oss_modules
else
  # If there are ALSA modules defined in /etc/modules.conf, but
  # ALSA is not yet loaded, then load the modules now:
  DRIVERS=`modprobe -c | grep -E "^[[:space:]]*alias[[:space:]]+snd-card-[[:digit:]]" | awk '{ print $3 }'`
  if [ ! "$DRIVERS" = "" ]; then
    echo "Loading ALSA kernel modules."
    for module in $DRIVERS; do
      modprobe $module
    done
  fi
  # If ALSA is now up, then load the mixer settings and OSS modules:
  if [ -d /proc/asound ]; then
    load_alsa_mixer
    load_alsa_oss_modules
  fi
fi
Due to my lack of experience with linux, I really don't know much about what the above actually does.

And in case it helps, /proc/modules content:

Code:
ndiswrapper 120980 0 - Live 0xe0459000
snd_pcm_oss 47908 0 - Live 0xe0427000
snd_mixer_oss 17344 1 snd_pcm_oss, Live 0xe0412000

Did you try running alsaconf? If it's not included with your distribution you can grab it from the Alsa FTP archive in the driver directory, IIRC.

Okay. I tweaked with it a little bit, and turns out that I had the kernel configuration wrong... For how long I don't know... as I forgot to turn my speakers back up... Here's what I've got in the kernel now, and it works:

Code:
#
# Advanced Linux Sound Architecture
#
CONFIG_SND=y
CONFIG_SND_TIMER=y
CONFIG_SND_PCM=y
CONFIG_SND_RAWMIDI=y
CONFIG_SND_SEQUENCER=y
# CONFIG_SND_SEQ_DUMMY is not set
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SND_VERBOSE_PRINTK=y
CONFIG_SND_DEBUG=y
# CONFIG_SND_DEBUG_MEMORY is not set
CONFIG_SND_DEBUG_DETECT=y
Hope this helps some other kid when they're in need

Thanks for the help everyone!
