Re: Setting up sound - alsa config Resolved
Resolved. I am not sure what exactly was the problem but I document here what I did.
First I recompiled the Kernel as suggested by Vin to enable the following
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
CONFIG_SND_SEQUENCER_OSS=y
Alsaconf still kept throwing messages that it cannot find any sound card even though it
was compiled in the Kernel. However alsamixer showed the sound card. Read the
documentation in /usr/share/doc/alsa-base to setup the device folders - by running
/usr/share/alsa/sndconfig
The last thing to do is to unmute the channels. Alsamixer lets one to do that. You might
have to pan the screen to the right to see all channels (it took some time for me to
figure that out).
The documentation on Alsa page is not very clear. Some of the things that I did are:
I precompiled all the supports in the kernel. It is not a must to compile them as
modules, as some of the documentation might lead you to believe.
I am running kernel 2.6.7, and it is not necessary to compile ALSA modules separately.
Check in dmesg that your support for sound card is loaded. Alsaconf might still show that
the device is not detected (I don't know why)
Install ALSA-base and alsa-utils using apt-get.
Go to Alsamixer and unmute the channels.
That should do it. I am not an ALSA expert. These were my exeriences, and I document
these so that it might help someone in future.
Thanks for all those who helped.
