Intel hdmi Alsa users please read if sound issues

(1/1)

Hi

I currently exceed attachement size and I forget which size to embed images....feel free to remind me

I have just installed this 64 bit distro and had no sound ....error message for using the legacy method for sound was
"something went wrong, sound not set up"



1) I have a new PC with onboard HDMI and onboard normal sound 3.5 mm outputs

2) When I ran the command

--- Code: ---aplay -l
--- End code ---
  it was not showing me the first card.....remember Alsa counts sound thingee by zero then 1,2 etc

3) when I ran lspci -vvv.....I can see 2 major sound things are discovered.....so the fault lay with my sound config
snip for hdmi is

The trick of course is to recognise that if your kernel is using the same module for both sound features.....use the index=number to force alsa to resolve the conflict.

###############

what follows is my current solution......there may be other ways.

1)  I chose not to have any blacklist option in my boot loader ......as its another distro booting TC at the moment.
2) I elected not to have any dot asoundrc file in my /home/tc as I am not using HDMI for output
3)  Using root powers I have this entry in my /opt/bootlocal.sh


--- Quote ---#!/bin/sh
# put other system startup commands here

/sbin/modprobe -r snd_hda_intel
/sbin/modprobe snd_hda_intel index=1
--- End quote ---

4) either log out to prompt or reboot and I currently have alsa-config in onboot list but I will test having alsa later.
5) I unmute and set volumes using alsamixer using the command


--- Code: ---alsamixer -c1
--- End code ---


6) Don't forget to store your new levels and look at persistence 

Hope that helps someone

Ok before I tidy up top post.....I deleted all saved volume files and swapped alsa into the onboot list and removed alsa-config,
no other changes

can not play a wav file  as per code box

--- Code: ---tc@box:~/Downloads$ aplay *.wav
ALSA lib conf.c:3512:(snd_config_hook_load) cannot stat file/directory /usr/local/share/alsa/cards/aliases.conf
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.default
aplay: main:722: audio open error: No such file or directory
--- End code ---

I then manually loaded alsa-config and could then play a wav file. 

--- Code: ---tc@box:~/Downloads$ tce-load -i alsa-config
libpci.tcz: OK
pciutils.tcz: OK
alsa-config.tcz: OK

tc@box:~/Downloads$ aplay *.wav
Playing WAVE 'Yamaha-EX5-Stereo-String-C4.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

tc@box:~/Downloads$  (meaning success)
--- End code ---

for me, I had to put alsa-config back into onboot and remove alsa as its a dependency of alsa-config

###################
2)  without any volumes saved and with alsa-config loading on full reboot I do get unmuted sound and some volume as per image
so all is not lost having to load one extra TCZ.



thats enough testing for today.
