 |
|
Hi. I"ve been fiddling with this for over a month now to no success. Any and all help would be appreciated.
As it stands I have basic sound support enabled in the kernel with a modular alsa driver. Before anyone offers, yes, I have attempted the in-kernel driver. It does not work either.
Anyway, alsa loads with only one error (involving the modem -- something I'm not terribly concerned with these days). I get a full set of mixer bars in alsamixer and can play with mutes and volume levels. But there is zero sound produced on either the speakers or over the headphones.
relevant information as follows. thanks for the help.

Could you send error message? Did you try | Code: | | cat /dev/urandom > /dev/dsp |
or? |

Error message is as above in $ dmesg.
$ cat /dev/urandom > /dev/dsp
yeilds nothing but speaker-test (which I didn't even know existed) yeilds nothing either.
As I stated, I'm not familiar with speaker-test. Is it reliant upon alsa properly detecting my output points (speakers) or is this now a hardware detection issue independent of ALSA? |

Sorry I did not see dmesg at first. Did you ran alsaconf ? Can you see the same error message with | Code: | | /etc/init.d/alsasound restart |
?
Speaker-test is part of alsa-utils and it is tone generator for ALSA. |

Yes to alsaconf and yes to init.d restart. The piece that can't be initialized is the modem (googling has told me that much). Now, I'm not sure if the problem bleeds out from there to affect audio production but if it's just the modem I don't have a huge use / concern for it.
Thanks for taking interest mirojira. |

update: I wrote a dirty bash script to try all the models available for intel-hda (see below).
no sound was produced throughout the whole affair. any ideas where I should go from here?
| Code: | #!/bin/bash
# alsatest-ihda.sh
# useful variables
MODELS_PATH="${0%/*}/ihda-models.dat"
OPTION_IHDA="options snd-hda-intel model="
ALSACONF_PATH="/etc/modules.d/alsa"
BKUP_PATH="/var/tmp/alsatest-ihda-models.alsa.bkup"
TMP_ALSACONF_PATH="/var/tmp/tmp.alsatest-ihda-models"
# our update / test commands
# four channels are used for (hopeful) completeness
function test_alsaconf {
modules-update
/etc/init.d/alsasound restart
speaker-test -c4 -l2
}
# first we save our existing configuration in case of crash of failure
if [ -f $BKUP_PATH ]
then
echo "alsatest: Backup already exists at ${BKUP_PATH}!"
echo "alsatest: Skipping backup..."
else
echo "alsatest: Backing up your existing alsaconf to ${BKUP_PATH}..."
cp $ALSACONF_PATH $BKUP_PATH
fi
# the guts of it
exec < $MODELS_PATH # reads in our models from file
while read line # loops
do
MODEL=$line # reads current model in
echo "alsatest: Changing ALSA snd-hda-intel model to: ${MODEL}"
sed "/${OPTION_IHDA}*/c${OPTION_IHDA}${MODEL}" $ALSACONF_PATH >> $TMP_ALSACONF_PATH # replaces options line in alsa conf
mv $TMP_ALSACONF_PATH $ALSACONF_PATH
echo "alsatest: Restarting ALSA and testing new model..."
test_alsaconf # runs the update and test
done
if [ -f $BKUP_PATH ]
then
echo "alsatest: Restoring the model to original before alsatest-ihda-models.sh..."
mv $BKUP_PATH $ALSACONF_PATH
modules-update
/etc/init.d/alsasound restart
else
echo "alsatest: Oh no! You've lost your backup!"
echo "alsatest: For now you're stuck with what you've got."
fi
echo "alsatest: Script finished." |

Your works on my box without any problems. From the error message above I can see that you have alsa-driver-1.0.14_rc2 installed. Last stable version in the portage is 1.0.14_rc1. Maybe you could try to downgrade. And maybe you could check what is wrong with patch_si3054.c which you can see in the error message aswell. I found this pach in kernel sources directories: | Code: | localhost # locate patch_si3054.c
/usr/src/linux-2.6.17-gentoo-r8/sound/pci/hda/patch_si3054.c
/usr/src/linux-2.6.18-gentoo-r6/sound/pci/hda/patch_si3054.c
/LFS/usr/src/linux-2.6.16.27/sound/pci/hda/patch_si3054.c |

| Has the no sound problem been with you from the start of having your PC? Or eg, did it stop working recently? Does sound work in other distros or Windows? I would boot a knoppix cd and see if it has sound. If so, figure out which kernel modules are loaded and do the same on your gentoo install. If sound is "configured" but just not coming out, check the audio cable is plugged into the right socket at the back of the pc. |

I'll take a look at it... though late last night I attracted the attention of an alsa dev who started pushing some custom scripts on me. They haven't worked for sound yet but suddenly new mixer bars have shown up in alsamixer so I think it's a step in the right direction.
Feel free to use the dirty script if you want but the dev actually reminded me that sometimes alsa volume states are reset (remuted) and so they need to be set. If you want to continue using it, I'd suggest the following.
| Code: |
BKUP_PATH="/var/tmp/alsatest-ihda-models.alsa.bkup"
TMP_ALSACONF_PATH="/var/tmp/tmp.alsatest-ihda-models"
++CTLS_REGEX="[Mm](aster|ASTER)|[Pp][Cc][Mm]|[Oo][Uu][Tt]|[Ll][Ff][Ee]"
++
++# unmutes and sets volume for all controls
++function amixer_ctls {
++IFS=$'\n' # changes the bash Internal Field Separator to only accept /n-ewline
++for AMIXCTL in $(amixer scontrols | egrep $CTLS_REGEX | sed 's/Simple mixer control //')
++ do
++ amixer -c 0 sset $AMIXCTL 95% unmute
++ done
++}
++
++# reloads alsa, sets volume
++function reload_alsa {
++ modules-update
++ /etc/init.d/alsasound restart
++ amixer_ctls
++}
--# our update / test commands
--# four channels are used for (hopeful) completeness
++# reloads alsa, sets volume, and runs speaker-test
function test_alsaconf {
-- modules-update
-- /etc/init.d/alsasound restart
++ reload_alsa
speaker-test -c4 -l2
echo "alsatest: Restoring the model to original before alsatest-ihda-models.sh..."
mv $BKUP_PATH $ALSACONF_PATH
-- modules-update
-- /etc/init.d/alsasound restart
++ reload_alsa |

There has never been sound on any linux distribution tried. (redhat, suse, ubuntu, debian, knoppix, and gentoo) Sound did work in windows. It's a laptop so the only possible 'cables' are the line-in and headphone jack. I'm certain the correct module is intel-hda however that particular driver allows for several different pin/nodule layouts (covered in the 'model' options). After speaking with a dev it has been suggested that my machine, the first they've seen of its kind (I'm fairly certain I'm the only person using gentoo on one), doesn't have a standard layout so we're trying to construct a new layout. (See the /proc...codec) |

I am using Gentoo on a very similar machine, if not the same type. Gateway MX3410 here. Anyway, did you get anywhere on this? |

im not sure if this would apply to the chipset that you have but i am also using the hda-intel drivers and to get it working i had to add
at the end of the kernel command in grub.conf and it works perfectly after. |
