Description Chuck Haines 2002-05-19 15:47:45 UTC
I have installed alsa 0.9_rc1 along with alsa-tools,alsa-utils and alsa lib and
it seemed to install fine.  I configured it for my card (a so9und blaster live)
like the doc files instructed.  Alsa starts fine (ie alsasound starts) with no
errors upon boot.  When I type lsmod I see the following:

amixer to unmute my speakers it seg faults as both root and as a normal user.

I hope I have provided all the information that is needed.  If anything else is
needed, please email me and I will get it as quickly as possible.  I scoured the
mailing lists and message boards but couldn't find anything relating to this.

Thanks.
Comment 1 Arcady Genkin (RETIRED) gentoo-dev 2002-05-19 23:19:23 UTC
What happens when you use any other alsa utility, like "alsamixer"? 
Comment 2 Arcady Genkin (RETIRED) gentoo-dev 2002-05-23 11:09:35 UTC
I can't reproduce it on two different machines with different alsa modules.  One
of them has a SB Live (emu10k1, just like you).

Can you post the output of the following command:

  qpkg -I '*alsa*'

Chuck, can you use other alsa utilities, like 'alsamixer'?
Comment 5 Chuck Haines 2002-05-27 14:08:21 UTC
I am able to use alsaplayer, but cannot hear anything.  I will try alsamixer 
tonite.
Comment 6 Seemant Kulleen (RETIRED) gentoo-dev 2002-07-03 21:52:58 UTC
what's news on this, chuck?
Comment 7 Chuck Haines 2002-07-04 12:19:21 UTC
Honestly, the machine I had this problem on no longer works.  So I'm gonaa close
the bug.  Sorry 'bout that.
