[SOLVED] Very low sound on my Slackware 14 64-bit

info.latawaz · 06-20-2013, 01:48 PM

Hi,

Today I played my first video on my new Slackware and the sound was there.

But I had to increase the level of sound to 70% approx to hear. This didn't happen in windows. On Windows, on level 20, the sound in headphones was so much that it was unbearable.

I haven't installed any driver as of now for audio but I think installing it should improve the output of audio.

Necessary Output.

Welcome to slackware.
I have 2 sound cards both using snd-hda-intel module. one is standard realteck ALC888 named SB, another is ATI radeon audio named HDMI. software mixing, and SB is my main card.
This my asound.conf file, it is working example. Replace sound card name SB to Intel for your card.

Code:

#
# DMIX output device
#
pcm.output {
      type dmix
      ipc_key 1234
      ipc_perm 0660
      slave {
              pcm "hw:0,0"
              period_time 0
              period_size 2048
              buffer_size 8192
              rate 44100
      }
      bindings {
              0 0
              1 1
      }
}

#
# DSNOOP input device
#
pcm.input {
      type dsnoop
      ipc_key 4321
      ipc_key_add_uid yes
      ipc_perm 0660
      slave {
              pcm "hw:0,0"
              periods 0
              period_time 0
              period_size 2048
              buffer_size 8192
              rate 44100
      }
}

#
# ASYM duplex device
#
pcm.duplex {
      type asym
      playback.pcm "output"
      capture.pcm "input"
}

ctl.duplex {
      type plug
      card SB
}

pcm.softvol {
      type softvol
      slave {
              pcm "duplex"
      }
      control {
              name "Pre-Amp"
              card SB
      }
      min_dB  -20.0
      max_dB   20.0
      resolution 20
}
ctl.softvol {
      type plug
      card SB
}

#
# Make the duplex device default
#
pcm.!default {
       type plug
       slave.pcm "softvol"
}

ctl.!default {
       type  hw
       card  SB
}

#aoss
pcm.!dsp {
        type plug
        slave.pcm "duplex"
}

#ctl device for xmms
ctl.!mixer {
        type hw
        card SB
}

Slackware 14 has additional alsa-plugins which includes plug for softvol, more volume adjustment, and alsa-plugins is not standard for 13.37, need to download from ALSA projects site.

my /etc/modprobe.d/sound.conf

Code:

# ALSA portion
alias char-major-116 snd
options snd major=116 cards_limit=2
alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-hda-intel
options snd-hda-intel id=SB,HDMI index=0,1 model=auto

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-slot-0 snd-slot-0
alias sound-slot-1 snd-card-1
alias sound-slot-1 snd-slot-1

# card #1
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 /dev/dsp0 snd-pcm-oss

# card #2
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-8 snd-seq-oss
alias sound-service-1-12 snd-pcm-oss
alias /dev/dsp1 snd-pcm-oss

need to reboot computer for alsa to take effects, I am using kms,
Hope it will help you anyway.

Where is this file? (Also if you can pass a command to find files, it will be bonus

Currently I am using 'whereis')

Quote:

whereis sound.conf
sound: /usr/src/linux/sound /usr/src/linux-3.2.29/sound /usr/include/sound

I don't have sound.conf file in /etc/modprobe.d/

Put asound.conf in /etc/

You have to create it.

info.latawaz · 06-22-2013, 02:28 AM

From what I infer, I have to add asound.conf in /etc/

And it's contents should be what? number22 gave the output of two different files. What should I put in the file /etc/asound.conf that I create. Also, what about the other output? Ignore that or put it in another file somewhere else?

Celyr · 06-22-2013, 03:06 AM

One fine is asound.conf put it in /etc/ (wich is the first one)
The other file is sound.conf, indeed you can change this name it's only important that you put it in /etc/modprobe.d/ (this is the second one). I suggest you also to read the modprobe.d readme file so you will understand what files here inside do.

info.latawaz · 06-22-2013, 05:11 AM

Celyr, thanks for your directions. As you asked, I read README file and now understand what is happening.

So as I have done the above and created both the files, do I have to make them executable or something? What do I do once I have created both the files?

Celyr · 06-22-2013, 01:13 PM

Well, about permission asound.conf should be root:root and 644

Code:

# chmod 644 file
# chown root:root file

about sound.conf you can chown it same as asound.conf and chmod it to 755.
After a reboot you should be ok, if not the issue was not there (and I'm sorry about that but I don't have such audio card).

info.latawaz · 06-24-2013, 01:14 AM

So I did all that. Now, when I restart, or start, I get a message. I have attached it's screenshot.

info.latawaz · 06-25-2013, 01:07 AM

The solution didn't work. Infact after adding those files, the sound card was no getting detected resulting in no sound at all. I am pretty happy with the sound that I have compared to no sound.
