A solution to online TV freezes
Appendix A. HDMI sound hack.
X Window Sytem
Install X as usual (skip Qt part of the „Toolkits“ page as you won't need Qt here).
If you need an example here's mine xorg.conf — nothing special here as everything was autodetected properly (HDMI is used).
If you need to use tv-out then here is the xorg.conf I wrote back when I was using tv-out. There are many comments there to show you the possible options.
One thing I should note: this LG TV was autodetected as having 300x300 dpi resolution (so fonts in GTK programs are large enough when you are 3-5 metres away from the TV).
If your TV was autodetected as having low dpi you can force whatever resolution you need by adding this to Device section of xorg.conf:
Option "UseEdidDpi" "FALSE" Option "DPI" "300 x 300"
Determine the driver first (load all of them):
# kldload snd_driver # cat /dev/sndstat [7:33:21] FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386) Installed devices: pcm0: <HDA Realtek ALC662 PCM #0 Analog> (play/rec) default pcm1: <HDA Realtek ALC662 PCM #1 Digital> (play) pcm2: <HDA NVidia GT21x HDMI PCM #0 DisplayPort> (play) pcm3: <HDA NVidia GT21x HDMI PCM #0 DisplayPort> (play) pcm4: <HDA NVidia GT21x HDMI PCM #0 DisplayPort> (play) pcm5: <HDA NVidia GT21x HDMI PCM #0 DisplayPort> (play)
As you can see the driver that worked is HDA. Add to /boot/loader.conf:
This system have two audio output options: pcm0-1 are motherboard sound channels and pcm1-5 are HDMI channels.
Just use motherboard sound if you connect to the TV via tv-out (no additional setup is needed usually) or switch the sound output to video card if you use HDMI.
HDMI sound output
To test the sound install a simple wav-player and download the test signal:
# cd /usr/ports/audio/waveplay # make install clean # rehash # cd # fetch http://daemon-notes.com/downloads/assets/misc/test.wav
Now switch to the first HDMI channel (pcm2) and play the sound:
# sysctl hw.snd.default_unit=2 # waveplay ~/test.wav
If you hear nothing switch to the next HDMI channel (hw.snd.default_unit=3) and play the file again. In the case with this GT210 pcm3 was the one that worked.
Add to /etc/sysctl.conf the correct call to enable HDMI sound:
If sound still doesn't work
GT210 needed a hack to get it working. If you have the same card or get "play interrupt timeout, channel dead" error then have a look at Appendix A.
