am running debian wheezy with the 3.2.0-3-686-pae kernel in intel desktop pc, the builtin sound card is not working so i just add the ESS Technology ES1983S Maestro-3i PCI Audio Accelerator sound card.
The sound card and speakers in the windows working properly.
I boot to the debian wheezy the lspci show the audio card but the wheezy didn't show the card in the alsamixer.
after google search i installed the alsa-firmware-1.0.25.tar.bz2 and the alsa-firmware-loaders_1.0.25-2_i386.deb now the wheezy show the sound card but still no voice.
The commands that troubleshoot sound in my idea shows that card is not properly loaded these are the result of some commands if some one can help:
