I hear no sound with pulseaudio, but I hear the "ready for login" sound after the x server starts. Instead of the script that loads module-loopback, you can also use module-bluetooth-policy which does exactly that. The snd-aloopmodule is very useful when you need to record other sound sources then your mi- crophone. It is geared towards audio production / recording though, so many applications do not have a JACK output driver; I haven't actively looked for it, but I believe it should be possible to route PulseAudio or even ALSA signals into JACK ports though. pactl load-module module-loopback source=0 sink=1 rate=44100 adjust_time=0 Once you enter the command, key in top in terminal and you should see pulseaudio is utilizing around 11-12% of your CPU power.

Things might actually be worse on older hardware with less optimised drivers than the Galaxy Nexus (I'd appreciate reports from running similar tests on a Nexus S or any other device with ALSA support to confirm this). The main difference from other transports, including PulseAudio TCP and RTP streaming, is the better quality of service when the latency is low (100 to 300 ms) and the network in unreliable (Wi-Fi). Xrdp is now supporting TLS […]. You can see information about sound interfaces by using "aplay -L" or "arecord -L". Flash does not like pulseaudio Youtube videos won't play at all and other sites play with no sound, pulse works with everything else though. c: Could not set format on sink bluez_sink. What is needed is: snd-aloop module will create a virtual card/device called Loopback, after `sudo modprobe snd-aloop` check with `aplay -l`. c: Could not set format on sink bluez_sink. I am however wondering if a separate source/sink pair is a better idea. I guess the other way round works too. A lot of tinkering. It is a drop in replacement for the ESD sound server with much better latency, mixing/re-sampling quality and overall architecture. Worst case, look in to "Jack" I've not used it personally, but I know it can do the same functions as aloop. It is intended to be an improved drop-in replacement for the Enlightened Sound Daemon (ESOUND). Use a loopback cable This is a simple and effective method of recording what is playing on the computer. PulseAudio is enabled by default on Ubuntu (except Lubuntu) and many other Linux distributions. You can also record your mix and mix this recording later to other Spotify tracks. Let’s first add the user ‘pi’ to the audio group to ensure it can use pulseaudio’s services: sudo usermod -Ga pulse-access pi Next, we’ll need to modify /etc/inittab to enable auto-login for user ‘pi’. This can happen for example during a suspend/resume. *Important: Take note of the number returned for each command. Re: Misterious audio loopback device I'm having the same issue after today's update. Using zita-ajbridge, it is also possible to add additional real sound cards into JACK. 0 Real-Time Digital Video Converter. I have looped sound from "Built-in Audio Analog Stereo" on both "Playback" and "Recording" on Pavucontrol which sends (or loops) the sound from Line In too Line Out.

Device instead, but that causes the script to attempt loading the loopback module before PulseAudio could load the bluetooth-device module, so the loopback module would fail to load. It seems that Echo doesn’t show itself as a Bluetooth input, I tried using Raspberry Pi with Raspbian, and a PC with Ubuntu, for both of them, I can only use Echo as A2DP streaming audio, but I can’t see it as microphone (no HSP profile). In order to install bettercap and download the caplet, you will need internet connectivity on the rpi, but we just freed wlan0 for injection, so you’ll either have to plug some ethernet adapter, smartphone in tethering mode, etc on the mini usb port now, or perform these steps while the board is still connected to your WiFi during.

Emma Joe Anderson. There will probably be a little bit of latency (echo) but it’s not hard to get used to. c: Cannot set requested sink latency of 2. That will return with the module number of the loopback module (14). ALSA has the optional alsaloop playthrough module in alsa-utils and PulseAudio has an optional module-loopback, but these modules may have noticeable latency and audio breakup. Pulseaudio. i did not think of loopback module because Audacity has a setting for 'Software playthrough of input' that can be used instead.
