Hello everyone, I'm trying to write some app that should show the user the available ALSA playback devices, and also show if the jack is plugged/unplugged.
As an example, on my laptop I have one card, and two devices: (1) $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 And I have a few controls associated with the card: (2) $ sudo amixer -c 0 controls numid=24,iface=CARD,name='HDMI/DP,pcm=3 Jack' numid=18,iface=CARD,name='Headphone Jack' [and some more] However, I really can't find *anywhere* how to relate (1) and (2) above. I see that pulseaudio is doing this, so it's obviously possible but I'm quite lost in the labyrinth of pulseaudio layers. Does anyone has an idea? Namely: how can I ask ALSA which controls belong to a given card,device tuple? Thanks a lot in advance! PS: I'll appreciate if nobody replies with "you could use pulseaudio" ;) -- Ezequiel García, VanguardiaSur www.vanguardiasur.com.ar ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
