On (06/03/14 09:18), Dave Woodfall <dave@xxxxxxxxxxxxxx> put forth the proposition:
mplayer reports no sound:
mplayer tv:// -tv driver=v4l2:device=/dev/video1:normid=8:alsa:adevice=hw.1:forceaudio:volume=80
...
Selected driver: v4l2
Opening video decoder: [raw] RAW Uncompressed Video
Audio: no sound
Does "mplayer something.wav" work?
Yes, mplayer works for wavs and other files..
Neither aplay -l nor -L list the device
Because the device is not used for playback.
Try "arecord -l".
% arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: CX20590 Analog [CX20590 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Cx231xxAudio [Cx231xx Audio], device 0: Cx231xx Audio [Conexant cx231xx Capture]
Subdevices: 1/1
Subdevice #0: subdevice #0
So it is listed at least. But arecord produces a silent .wav when I use it:
arecord -f dat -D hw:CARD=Cx231xxAudio,DEV=0 test.wav
Success. I used the second command mentioned on the linuxtv wiki:
mplayer tv:// -tv
driver=v4l2:device=/dev/video1:normid=8:alsa:adevice=hw.1:forceaudio:volume=80:immediatemode=0:width=720
Still no sound through arecord though.
