[SOLVED] Slackware 14.0: ALSA still seems not to work out of the box with Realtek ALC887-VD.

I have just installed Slackware 14.0 and experienced some difficulty running ALSA. The fact is I did not have audio output, despite TobiSGD's oppinion it must run out of the box with 14.0. Note this is HDA-Intel, with Realtek ALC887-VD as the controller proper. Here is what I did given the facts:

(a) I copied /lib/modprobe.d/sounds-modems.conf to /etc/modprobe.d and,
after modifying it, this is its contents:

Code:

blacklist snd-atiixp-modem
blacklist snd-intel8x0m
blacklist snd-via82xx-modem

alias snd-card-0 snd_hda_intel
alias sound-slot-0 snd_hda_intel
#options snd_hda_intel model=auto position_fix=3 (lo use comentado y sigue asi)
options snd_hda_intel index=0 model=auto 
options snd_pcsp index=1

(b) Then 'modprobe snd_hda_intel' and was accepted. Then

Code:

        # cat /proc/asound/cards
        0 [PCH        ]: HDA-Intel  -  HDA Intel PCH
                         HDA Intel PCH AT 0xloquesea irq 41

But alsamixer would say:

Code:

semoi@server:~/Desktop$ alsamixer
cannot load mixer controls: Invalid argument
semoi@server:~/Desktop$

(c) On the other hand,

Code:

  
root@server:~# alsactl init
Found hardware: "HDA-Intel" "Realtek ALC887-VD" "HDA:10ec0887,1458a002,00100302" "0x1458" "0xa002"
Hardware is initialized using a generic method
/usr/share/alsa/init/default:26: control element not found
/usr/share/alsa/init/default:26: control element not found
/usr/share/alsa/init/default:48: control element not found
root@server:~#

I still don't understand what happens. Do you? Thanks in advance.

Probably a hardware specific issue for which you have not supplied sufficient information to provide further advice.

Moved to the Slackware forum as requested by the OP.

In my opinion, your approach is way too complicated. I never run any modprobe alias commands, I just enter

Code:

aplay -l

into the terminal and look for the number of my card. I have a USB card that is hw:2,0 so this ~/.asoundrc sets it as the default device:

Code:

#Define the default device via "aplay -l"
pcm.snd_card {
        type hw
        card 2
        device 0
}

#Define the default control
ctl.snd_card {
        type hw
        card 2
        device 0
}

pcm.!default {
    type            plug
    slave.pcm       "snd_card"
}

If it still can't find any mixer controls, you can try adding a virtual one for yourself. Note that it only shows up after you first used the sound card:

Code:

#Define the default device via "aplay -l"
pcm.snd_card {
        type hw
        card 2
        device 0
}

#Define the default control
ctl.snd_card {
        type hw
        card 2
        device 0
}

pcm.!default {
    type            plug
    slave.pcm       "softvol"
}

pcm.softvol {
    type            softvol
    slave {
        pcm         "snd_card"
    }
    control {
        name        "Master"
        card        2
    }
}
