![]() ![]() When using dark theme it is also possible to change the height of the seekbar and size of the toolbar buttons.Using audacity to record audio from a Chromium webpage, audacity consumed about 30% of the CPU, chromium consumed about 37%, and pulseaudio consumed less than 10%.sigh!), I decided sorting out PulseAudio was easier. I'm quite sure there's a way to make it work with alsa, but based on my prior dive into it (which I failed to document. I havent' investigated why it's only Mono.But, I didn't test whether this somehow mucked up the "standard" audio configuration. I did export an audacity mp3 and play it on my desktop system, which worked fine. A bit of a hassle to set up, but you only need to do the settings in pavucontrol once, unless you change them for another reason. ![]() PulseAudio seems to nicely remember it's settings, and also sets itself up to restart when the current user logs in again. Start audacity recording, and then on pavucontrol's Recording tab, ensure that ALSA plug-in is set to record from "Monitor of Built-in Analog Mono".On pavucontrol's Playback tab, change the app's "playback on" setting to be the "built-in audio analog mono" if it is not set to this.Start the app you want to record, and have it generate some sound (e.g., browser or vlc playing a video or audio stream).=> Tempo and Height are too low according to this ratio, but the sampling rate must remain at 44.1 kHzī) It would be nice to have a start/stop feature without rebooting for this tool (maybe as a service or a script ?)Ĭode: Select all sudo apt install pavucontrol audacity On the other hand, some problems remain to be solved if we want a generic and user friendly capability :Ī) I had to post process the files with Audacity on my Desktop PC to increase the Speed by a 1.088 ratio (48000/44100) asoundrc file in ~/ so I simply installed yours and rebootģ° Every time some sound is played through my HDMI 0 port, a mp3 file is created in /tmp with good naming convention, thanks to your rc fileĤ° This works for Chrome and for VLC as well, and confirms that any sound of the desktop is recorded Here is my report :ġ° With a raspbian_full distribution, you need to install the "lame frontend" to get the "lame" commandĢ° With a raspbian_full distribution, I had no. Well, thanks again tvjon, this seems to be a good start to solve the problem. There are many packages from Debian ARMHF which have compatibilty issues, it is not feasible for RPT / RPF to test them all. If it doesn't, oh well, blame it on Linux randomness, which is a Linux "feature" I bet that a lot of the more seasoned Linux users of this forum have a software package or two for which they have similar perspectives. I read comment as not liking pulseaudio, and/or he's aware of some scenarios where it doesn't work, or knows some set of issues with it. It worked the last time I took it for a spin (which I may do again.). It's included, which means it at least compiles and, more likely than not, works. If it were truly not supported, it wouldn't be included. pulseaudio is included in the Raspbian distro, as are a large collection of various bits of software. With apologies to if I'm incorrect, but I don't read either his statement or the statement that posted, as statements of "non-support" (not sure what that means, actually). From a user point of view, everything should still work exactly as before – the only change is that if you still wish to use PulseAudio for some other reason, you will need to install it yourself.įri 5:56 am : This is just one of several messages where a team member says to avoid installing pulseaudio. PulseAudio is therefore no longer installed by default, and the volume plugin on the taskbar will no longer start and stop PulseAudio. For Stretch, we are using the bluez-alsa package to make Bluetooth audio work with ALSA itself. In Jessie, we used PulseAudio to provide support for audio over Bluetooth, but integrating this with the ALSA architecture used for other audio sources was clumsy. This change was made when Raspbian Stretch was released: Please provide a reference for pulseaudio not being supported by the Raspberry Pi team. As said above, pulseaudio is fine but is not supported by Raspberry Team, and this is a drastic limitation of this board which can't be seen as a desktop replacement for this reason at least ![]()
