![]() This will force PulseAudio to use only 48kHz (everything else is resampled as usual). Until then, add/modify these lines in /etc/pulse/nf to work around this bug: default-sample-rate = 48000 The fix should be released with the next version of PulseAudio (probably version 4.1). There is also a bug in PulseAudio that is triggered when PulseAudio switches between 44.1kHz and 48kHz audio. To disable 'flat-volumes', add/modify this line in /etc/pulse/nf flat-volumes = no This seems to be the default setting in Ubuntu, but not in Arch Linux, so you may want to check this. There are two ways to do this: the easy one and the hard one.īefore you do any of this, I highly recommend that you set the PulseAudio setting 'flat-volumes' to 'no', otherwise you won't be able to control the volume of applications individually (or at least not in a sane way). Consider using JACK instead.Ĭredit goes to Joshua Hertlein for figuring this out. This method is know to be buggy and will likely result in some stuttering. Recording game audio and microphone at the same time If you want to switch back, just select an audio source that is not a monitor. Select an audio source that starts with 'Monitor of'. Make sure that the audio backend is set to PulseAudio. Using PulseAudio Recording only game audioĪssuming you have PulseAudio, you can follow these steps: You should also disable 'auto mute' if your speakers become muted when you plug in the cable. It's primitive but it works very well, you just have to adjust the recording level in 'alsamixer' to get the volume right. To my knowledge, there is no reliable way to record the speakers in ALSA except by physically connecting the line out/headphone jack to the line in/microphone jack with a cable. JACK is harder to set up, but I think it's worth it. If you care about reliability and sound quality, I recommend using JACK instead. PulseAudio works, but is sometimes unreliable and it still has some bugs that you may run into when you try to do more advanced things with it (such as the commands needed to record a game and a microphone at the same time). PulseAudio is enabled by default on Ubuntu (except Lubuntu) and many other Linux distributions. There are two ways to do this: either through PulseAudio or through JACK. Sometimes you don't want to record your microphone, but the audio from the game you're playing.
