HI,
When you do the alsaconf and it finds the sb, it asks about installation. Jot the file name snd_sb ?? and save for later. You should be able to manually

then, after a reboot and the sound works ?
Iadd a line to your /etc/init.d/bootmish.sh to have the system do that for you on boot up. also as root;
# echo "modprobe snd_sb ?? " >> /etc/init.d/bootmish.sh
will do that step.

Post subject:	sound card not recognized at boot
I'm currently testing KnoppMyth (R5A16) . I'm using an old box I had lying around, and put a WinTV PVR-500MCE in it. Not having used KnoppMyth before, and being a Linux newbie, it took a lot of reading, but I finally got the PVR-500 card to show the TV picture, using ptune-ui.pl. and either cat /dev/video0 > input.mpg \| xine input.mpg or mplayer -vo xv /dev/video0. However, I still have a problem. The soundcard in the box is old, a SoundBlaster Vibra16C PnP (yes,it's an ISA card). When the machine boots, the sound card is recognized Code: Sep 18 04:04:26 kg-mythtv kernel: pnp: SB audio device quirk - increasing port range Sep 18 04:04:26 kg-mythtv kernel: isapnp: Card 'Creative ViBRA16C PnP' Sep 18 04:04:26 kg-mythtv kernel: isapnp: 1 Plug & Play card detected total but for some reason, the necessary modules aren't loaded, and /var/log/mythtv/mythbackend.log contains errors like this: Code: 2005-09-20 06:00:41.461 Could not open audio device: /dev/dsp After running 'alsaconf' and getting it to probe legacy devices, the necessary modules for the sb16 card are loaded, and it works. How can I make this happen at boot? Ie. what is the correct way to configure this?

You should be able to manually I have even tried alsaconf --config /root/alsaconf.txt (where /root/alsaconf.txt is an existing file, with write permissions, and non-empty). No matter what I do; alsaconf will not write to any config file, for some strange reason. (The default is /etc/modprobe.d/sound, but alsaconf doesn't write to that one either). Quote: # modprobe snd_sb ?? I have tried modprobe snd-sb16 after boot, but still the sound doesn't work. When I look at the output of 'lsmod' it differs slightly from when I do alsaconf first. lsmod after 'alsaconf'(only the sound part): Code: Module Size Used by snd_sb16 12392 0 snd_opl3_lib 10496 1 snd_sb16 snd_sb16_dsp 11136 1 snd_sb16 snd_pcm 79364 1 snd_sb16_dsp snd_timer 22532 2 snd_opl3_lib,snd_pcm snd_page_alloc 9348 1 snd_pcm snd_sb16_csp 19840 1 snd_sb16 snd_sb_common 14976 3 snd_sb16,snd_sb16_dsp,snd_sb16_csp snd_hwdep 9248 2 snd_opl3_lib,snd_sb16_csp snd_mpu401_uart 7936 1 snd_sb16 snd_rawmidi 21536 1 snd_mpu401_uart snd_seq_device 8716 2 snd_opl3_lib,snd_rawmidi snd 47460 11 snd_sb16,snd_opl3_lib,snd_sb16_dsp,snd_pcm,snd_timer,snd_sb16_cs p,snd_sb_common,snd_hwdep,snd_mpu401_uart,snd_rawmidi,snd_seq_device soundcore 9312 1 snd lsmod after 'modprobe snd-sb16': Code: Module Size Used by snd_pcm_oss 48032 0 snd_mixer_oss 18048 1 snd_pcm_oss snd_sb16 12392 0 snd_opl3_lib 10496 1 snd_sb16 snd_sb16_dsp 11136 1 snd_sb16 snd_pcm 79364 2 snd_pcm_oss,snd_sb16_dsp snd_timer 22532 2 snd_opl3_lib,snd_pcm snd_page_alloc 9348 1 snd_pcm snd_sb16_csp 19840 1 snd_sb16 snd_sb_common 14976 3 snd_sb16,snd_sb16_dsp,snd_sb16_csp snd_hwdep 9248 2 snd_opl3_lib,snd_sb16_csp snd_mpu401_uart 7936 1 snd_sb16 snd_rawmidi 21536 1 snd_mpu401_uart snd_seq_device 8716 2 snd_opl3_lib,snd_rawmidi snd 47460 13 snd_pcm_oss,snd_mixer_oss,snd_sb16,snd_opl3_lib,snd_sb16_dsp,snd _pcm,snd_timer,snd_sb16_csp,snd_sb_common,snd_hwdep,snd_mpu401_uart,snd_rawmidi,snd_seq_device soundcore 9312 1 snd Quote: then, after a reboot and the sound works ?

Now I know where to put it, when I find the right command to enable my soundcard. Quote: Old stuff is a great way to learn, just have patience I agree. Thanks for your time and help.

Hi, You may need to run alsamixer to unmute and set levels, I think it saves properly if run as root. Mike

This topic is nearly a year old, but I had to do the same thing for a new Sound Blaster Live! Value card. The "Value" part is apparently a Dell-specific chipset that doesn't actually work with SB drivers (for Linux). There is much written on this elsewhere. FYI, out of the box, KnoppMyth had no sound with this card. I ran alsaconf, which turned on the sound, but lost the sound after reboot. Adding "modprobe snd-emu10k1x" to the end of /etc/init.d/bootmish.sh still does the trick. Is this still the appropriate fix?

I think this is the known issue this Dell Soundblaster. If the fix works, it works!

HI Nyhm, Curious, what flavor of Dell? I have mostly had issues with the OptiPlexGX1 needing a modprobe snd-cs4236 The GX260-270s I think required modprobe snd-intel8x0 but that was for ~A16? older Compaq Desktop Pro neads modprobe snd_es1688 for A26 Mike after thought, some topics never die

Mike, I have a Dell Dimension 4600. It has an Intel motherboard sound chipset, but I went for the Sound Blaster Live! upgrade. Then I found that I couldn't use this "special" SB in Linux (Debian), which was a big disappointment (with Dell and Sound Blaster, not Linux). With blind hope, I put the card into the KnoppMyth R5C7. It didn't work until I found this post about manually doing a modprobe. Apparently, snd-emu10k1x handles these "special" SB Live! cards.
