Hi Tanu, I am attaching an output of pactl list, which contains all the sources and sinks detected when a speaker having 4 identical sound cards was plugged in. Sinks 1 to 5, are the Speaker sinks, alsa.card_name = "C-Media USB Headphone Set" alsa.long_card_name = "C-Media USB Headphone Set at usb-0000:00:1a.0-1.1.3, full speed" card_name is same for all sound cards, and long_card_name includes the usb address, which again is dependent upon the system. Is there some serial number component, like mac-id in network devices, which is unique for sound cards ? Thanks, Amar Akshat On Fri, Oct 19, 2012 at 2:52 AM, Tanu Kaskinen <tanuk at iki.fi> wrote: > On Thu, 2012-10-18 at 17:13 +0900, Amar Akshat wrote: >> Hi, >> >> Is there a unique way of determining any sound card via PulseAudio? >> >> Write now I identify the sound cards by the alsa.card = "0" parameter, >> which shows up in pactl list.
