[MPlayer-users] Mencoder problem with /dev/dsp

[Prakash Sompura]

Thanks for an excellent information. I have done the same what is said in
the link you have sent. I have connected audio-out of my SAA7130 card to
sound-in of my on-board sound device. However when I play TV with following
command of MPlayer  I get excellent picture and sound. Still I am not able
to increase/decrease sound volume by 0/9 keys.

mplayer -ao pulse -tv
forceaudio:driver=v4l2:automute=1:outfmt=yv12:amode=1:volume=10:decimation=1
-vo xv tv://

My on-board audio card is: (cat /proc/asound/cards)

0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0x902c0000 irq 28

Also I have attached screenshot of "alsamixer -c 0" command. Output of
"alsaunmute" command is:

Unknown hardware: "HDA-Intel" "Realtek ALC662 rev1"
"HDA:10ec0662,8086d604,00100101" "0x8086" "0xd604"
Hardware is initialized using a guess method

Please help.
