  1. no sound after compiling kernel 2.6.11.6

    Hello,

    For the first time I successed to compile a linux kernel (from 2.4.26 to
    2.6.11.6). Everything is working fine except from the sound module.
    If I'm right I need the snd-op13sa2 module. So that's the modules I
    compiled.

    This what I got from lsmod.

    root@linux:~# lsmod
    Module Size Used by
    snd_opl3_lib 9024 -
    snd_hwdep 6816 -
    snd_cs4231_lib 23520 -
    snd_mpu401_uart 6208 -
    snd_rawmidi 20000 -
    snd_pcm_oss 48608 -
    snd_pcm 84392 -
    snd_page_alloc 7460 -
    snd_mixer_oss 17376 -


    There's only one module missing. (if I'm right)

    root@linux:~# modprobe -c | grep opl3
    alias pnp:cYMH0020dYMH0021* snd_opl3sa2
    alias pnp:cYMH0030dYMH0021* snd_opl3sa2
    alias pnp:cYMH0800dYMH0021* snd_opl3sa2
    alias pnp:cYMH0801dYMH0021* snd_opl3sa2
    alias pnp:cNMX2200dYMH2210* snd_opl3sa2
    alias symbol:snd_opl3_create snd_opl3_lib
    alias symbol:snd_opl3_timer_new snd_opl3_lib
    alias symbol:snd_opl3_new snd_opl3_lib
    alias symbol:snd_opl3_regmap snd_opl3_lib
    alias symbol:snd_opl3_hwdep_new snd_opl3_lib
    alias symbol:snd_opl3_init snd_opl3_lib
    alias symbol:snd_opl3_reset snd_opl3_lib
    alias symbol:snd_opl3_interrupt snd_opl3_lib

    I don't understand all of this output but I thought I should use the
    snd_op13sa2 module:
    Code:
    root@linux:~# modprobe snd_opl3sa2
    FATAL: Error inserting snd_opl3sa2 (/lib/modules/2.6.11.6/kernel/sound/isa/snd-opl3sa2.ko): No such device
    root@linux:~# cd /lib/modules/2.6.11.6/kernel/sound/isa/
    root@linux:/lib/modules/2.6.11.6/kernel/sound/isa# insmod snd-opl3sa2.ko
    insmod: error inserting 'snd-opl3sa2.ko': -1 No such device

    emz... strange? What's wrong here? And how could I make my sound working
    again?

    Greetz,

    First of all, in the 2.6 kernel the default sound system has changed
    from OSS to ALSA. OSS is still supported, but ALSA is supposed to be
    better. Then, you also need the module-init-tools package, plus maybe a
    few others. The best you can do is google a little for "upgrade kernel
    2.4 2.6".

    A first suggestion (might not work): perhaps snd-opl3sa2 depends on
    another module, which isn't loaded. Did you do a "depmod -a" after
    installing the new kernel ?
    The second suggestion: try the upgrade system of your distribution to
    get to kernel 2.6. Once you have the system running, you can customize
    the kernel as you wish.
