Speakers do not work but headphones do

I've just installed alsa and other necessary tools. But i can't make my speakers work. When plugging headphones everything is ok. The OS is running on Acer Aspire 1410. I've already tried different settings in alsamixer without any help. What should I do to make my speakers work?

lsmod | grep snd

Re: Speakers do not work but headphones do

Obvious question: are you sure it's not a hardware problem, do the speakers actually work?
I'm using an Acer Aspire A110 and I have snd-pcm-oss in /etc/modules-load.d for some reason. I don't remember why I put it there, but you could try modprobing it.

lsmod |grep snd

snd_hda_codec_realtek    52472  1 
snd_hda_intel          22257  4

snd_hwdep               4843  1 snd_hda_codec
snd_pcm_oss            33446  0
