Bug 27934 – no sound, equilizer bars move, alsamixer/volume maxxed and unmuted

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Monica Jae 2003-09-04 09:45:18 UTC]

from linux-2.6.0-test2-bk8, linux-2.6.0-test3-bk1 to linux-2.6.0-test4 i cannot
get any sound what-so-ever.  I submitted another bug, but retracted it for some
reason, but it was never resolved, i just went back to the pre2 kernel.  I
emerged alsa-drivers, alsa-utils, alsa-tools.  Alsamixer channels are ALL
unmuted and MAXXED!  THe equilizer on xmms shows activity, but of course i get
no throughput nor output.  all sound card modules are loading correctly and with
no errors at boot...
my /etc/modules.d/alsa:
# ALSA portion
         
          alias char-major-116 snd
# OSS/Free portion
          
          alias char-major-14 soundcore

##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
##  ALSA portion
## alias snd-card-0 snd_intel8x0
         
          alias snd-card-0  intel8x0

## alias snd-card-0 ac97_codec
## alias snd-card-1 snd-ens1371
##  OSS/Free portion

        alias sound-slot-0 snd-card-0

##alias sound-slot-0 ac97_codec
## alias sound-slot-1 snd-card-1
##

# OSS/Free portion - 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
##  OSS/Free portion - card #2
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss

        alias /dev/mixer snd-mixer-oss
        alias /dev/dsp snd-pcm-oss
        alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.
        options snd cards_limit=1

so, i hope you guys can help me, i was in the forum, but the problem there for
someone else was a muted PCM.

thanks

alsa is part of 2.6.x kernel, use the drivers in that 
 
dont use the drivers that are part of the alsa-drivers pkg 

[Comment 2 Monica Jae 2003-09-04 10:54:23 UTC]

i did initially, but ok, so i'll just emerge --unemerge everything alsa? (tools, utils, drivers?)

[Comment 3 Monica Jae 2003-09-04 10:58:26 UTC]

also, what should i do with /etc/modules.d/alsa and /etc/inid.d/alsasound

[Comment 4 Monica Jae 2003-09-04 11:19:02 UTC]

i removed alsa-drivers and tools and utils and ... voila!! SOUND!  haha, how exceedingly simple... you guys rock thank you so much! :* :)

[Comment 5 SpanKY 2003-09-04 12:00:36 UTC]

i dunno about the utils/tools packages but i know drivers are useless when 
running 2.6.x 
 
could you investigate a little into it and post your findings so that in the future 
ppl have something to read ? 

[Comment 6 Monica Jae 2003-09-04 12:16:34 UTC]

well, i don't know if this is related, but sound is very distorted when playing mp3's now through xmms--any ideas?

i don't know what it is you want me to post, but i unmerged alsa-utils, and alsa-tools and now i have sound.

/etc/modules.d/alsa is still there, but i "rc-update del alsasound" and it removed it from boot

[Comment 7 Markus Nigbur (RETIRED) 2003-12-05 23:05:02 UTC]

alsa-{tools,utils} are still 'needed', as they provide alsa-mixer and the like, also you can still use the /etc/init.d/alsasound initscript to automatically unmute your mixer devices on startup.

to comment #6: you probably moved all mixer levels to 100%, 78% are recommend.

[Comment 8 Andrew Cooks (RETIRED) 2003-12-05 23:20:05 UTC]

Could http://www.gentoo.org/doc/en/alsa-guide.xml be updated to explain what alsa-utils and alsa-tools do and spell out what to do for 2.6?
