![]() ![]() Once the USB soundcard is detected and initialised correctly, you can solve the other problems. I suggest you fix this issue first because all following steps rely on a solid hardware detection. You should verify if plugging and un-pluging the device works fine (check your /var/log/messages with tail -f while pluging / un-pluging your USB card). ![]() The multiple copies of your USB soundcard which are listed for each port it was plugged in seem to indicate issues with udev. My old SB Live Gamer, for example, reports tons of I/O, controls and switches in the ALSA mixer even if they aren't external usable. ALSA lists pretty much any device / control on your soundcard even if there might be no plugins available. There are both digital and analog devices listed for sound cards mainly because they HAVE digital and analogue I/O. Now lets head on to the questions I think I have destilled from your writings. Your posting looks like a mess and makes it hard to read what you really want.Īt least post short descriptive questions in a structured way (listed / numbered) ! So what is the proper way of setting primary and secondary sound cards in this situation? Too much confusion! All that mess for just two different cards. What about that Phonon? Would it override the nf if I set default device there? Why there are so many different devices in the Phonon configuration list:Ĭ-Media USB Headphone Set, USB Audio (Default Audio Device)Ĭ-Media USB Headphone Set, USB Audio (IECblablabla)Īnd that C-Media triplet for every USB port the CM118 has been plugged in. I guess I can uninstall OSS without worries as no one seems to need it (checked with "whoneeds"). ![]() The only way to do this is to write some kind of script, right?ĪFAIK the following audio components are installed: ALSA, OSS (for some unknown reason), Phonon, Gstreamer. For example, if I plug out the USB card and then run some application like Clementine or Firefox there would be no sound ("connection refused" in Clementine).Īlso kMix/amix should switch the master channel from HDA Intel Master to C-Media Master automatically. The problem is that most of the time it doesn't work. The internal SC should take over when CM118 is unplugged. No need for audio streaming or any other luxuries.Īll the applications should use the USB card whenever it's plugged in. Per-application sound control would be nice but if that adds too much clutter, I could live without it. I just need playback and/or recording support for these applications: opera, firefox, skype, clementine, mplayer, vmplayer. * Some more info On all the USB Ports not only is the headphone is recognized as 'C-media' but also, for some months, my Nokia Lumia 920 is not being recognized as a device-the phone used to.**** List of PLAYBACK Hardware Devices ****Ĭard 0: Set, device 0: USB Audio Ĭard 1: Intel, device 0: AD198x Analog Ĭard 1: Intel, device 1: AD198x Digital įirst of all, why are there both analog and digital subdevices? May be I could delete some registry key and/or some driver dll files to remove some caching to start from scratch but don't know which files to delete? The headphone is fine-works fine in my Windows 8 Acer W510 tablet. Also, note I never needed any installation media nor were they supplied. I have downloaded software from but those did not work. Or driver files are not being found online. My hunch is that either PNP is not working fully-uninstalling and re-inserting does put the device back into the unknown part. Note, the driver always listed as 'C-media USB Headset'. But now the device shows up as 'C-media USB headset' in the 'unknown' devices part of Device Manager with no drivers and any automatic search is unable to find the drivers. I have a USB headset (made by Gigaware) which has been working fine for years in my Win 7 machine. ![]()
