Hi all,
I am trying to extract from the aplay -l output the Card and Device numbers. I had a script that was working but found another motherboard that has an EXTRA word. HDA Nvidia and HDA ATI HDMI is what I am talking about below.
how do I search for a line that has HDMI (which I know how to do), then ignore everything upto the device work and take the next field after that?
Thanks,
Jerry
I was doing this but it does not work for both cases. AUDIO_HDMI=`aplay -l | grep -c HDMI` if [ "$AUDIO_HDMI" -ge 1 ] then AUDIO_DEVICE=`aplay -l | grep HDMI | grep " device " | grep -m 1 -v "device 0" | tr -d ':' | cut -d ' ' -f 8` AUDIO_CARD=`aplay -l | grep HDMI | grep " device " | grep -m 1 -v "device 0" | tr -d ':' | cut -d ' ' -f 2` sed "0,/hw:/s/hw:.*/hw:$AUDIO_CARD,$AUDIO_DEVICE"/" < /etc/asound.conf > tt.txt mv tt.txt /etc/asound.conf
card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0
card 2: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI] Subdevices: 0/1 Subdevice #0: subdevice #0
