Ubuntu
alsa-driver package

I am stuck in a GNU Nano install

Asked by hgrahamprc@gmail.com

I have sound problems with 9.04, the volume is too low. Following Ubuntu Documentation/SoundTrouble instructions I discoverd I had

00:01.1 SMBus: nVidia Corporation MCP55 SMBus (rev a3)

        Subsystem: ASUSTeK Computer Inc. Device 8239

        Flags: 66MHz, fast devsel, IRQ 5

        I/O ports at ff00 [size=64]

        I/O ports at 1c00 [size=64]

        I/O ports at 1c40 [size=64]

        Capabilities: <access denied>

        Kernel driver in use: nForce2_smbus

        Kernel modules: i2c-nforce2

and used

!!ALSA Version
!!------------
Driver version: 1.0.18rc3
Library version: 1.0.18
Utilities version: 1.0.18

following tag v1.0.18rc3 from projects/alsa-kmirror.git/summary
I found in Realease v1.0.18rc3 ALSA-Configuration.txt

        AD1988/AD1988B/AD1989A/AD1989B
 987 6stack 6-jack
 988 6stack-dig ditto with SPDIF
 989 3stack 3-jack
 990 3stack-dig ditto with SPDIF
 991 laptop 3-jack with hp-jack automute
 992 laptop-dig ditto with SPDIF
 993 auto auto-config reading BIOS (default)

My system has six jacks.

Now comes my problem. The following 3 commands are suggested.

sudo nano /etc/modprobe.d/alsa-base.conf
options snd-hda-intel model=6stack
sudo alsa force-reload

After the first command I get the output below and I do not know how to proceed.

  GNU nano 2.0.9 File: /etc/modprobe.d/alsa-base.conf

I found out nano is a text editor and I used it as above to open file alsa-base.conf and added the line

options snd-hda-intel model=6stack

and saved the file. Other options were also listed in the file

options bt87x index=-2
options cx88_alsa index=-2
options saa7134-alsa index=-2
options snd-atiixp-modem index=-2
options snd-intel8x0m index=-2
options snd-via82xx-modem index=-2
options snd-usb-audio index=-2
options snd-usb-us122l index=-2
options snd-usb-usx2y index=-2
options snd-usb-caiaq index=-2
# Ubuntu #62691, enable MPU for snd-cmipci
options snd-cmipci mpu_port=0x330 fm_port=0x388
# Keep snd-pcsp from beeing loaded as first soundcard
options snd-pcsp index=-2

options snd-hda-intel model=6stack

This made the sound performance worse. When I tried to open the file again with nano to remove the new line nano showed

GNU nano 2.09 File:/ect/modprobe.d/alsa-base.conf

However I can not open the file to edit it.
My questions are how do I now get nano to open the file for editing and what should I edit in or out to try to improve the sound?

After reboot nano loaded alsa-base.conf for editing. I deleted the line

options snd-hda-intel model=6stack

and saved the file. I then ran the command

sudo alsa force-reload

Then I went to medibuntu and installed the packages there and rebooted. I then clicked on the sound icon located in the upper right of the screen and clicked on volume control. I adjusted all setting to maximum volume.

Now the sound works great.

I am not sure what steps made the improvement in the sound but I am happy it is working well now.

Thanks for the help.
