As a plain ALSA (or sometimes, but very seldom jackd + ALSA backend user) I set up the default device by $HOME/.asoundrc . I don't know if pulseaudio takes care about this default. I don't use pulseaudio. When using jackd, I need to get rid of $HOME/.asoundrc , before using jackd. Don't be confused by my output, the first card is card 0 and the second card is card 3, because I set up placeholders by /etc/modprobe.d/alsa-base.conf . This is completely irrelevant for you, it just explains why the output of aplay might be confusing on my machine. • rocketmouse@archlinux ~ $ cat /etc/modprobe.d/alsa-base.conf # ALSA module ordering options snd slots=snd_hdspm,snd_ice1712,snd_ice1712 When not using jackd, but just plain ALSA, I want audio output via HDMI. • rocketmouse@archlinux ~ $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: HDSPMx579bcc [RME AIO_579bcc], device 0: RME AIO [RME AIO] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: PCH [HDA Intel PCH], device 0: ALC897 Analog [ALC897 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: PCH [HDA Intel PCH], device 1: ALC897 Digital [ALC897 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: PCH [HDA Intel PCH], device 3: HDMI 0 [EV2450] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3] Subdevices: 1/1 Subdevice #0: subdevice #0 This is my $HOME/.asoundrc : • rocketmouse@archlinux ~ $ cat .asoundrc defaults.pcm.card 3 defaults.pcm.device 3 Again, I don't know if pulseaudio cares about $HOME/.asoundrc . However, for such simple Intel audio devices you usually don't need to do something complicated, to use several apps at the same time. A sound server isn't required to grant access to the audio device, this happens automagically under the hood. Right now on my machine Jimi Hendrix plays Voodoo Child on Waterfox and Little Wing on Firefox via Intel HDMI. As long as you don't need something tricky such as Bluetooth or pro-audio, you much likely don't need a sound server at all. When using my snd_hdspm, snd_ice1712 or an USB Scarlett 18i20 it's not as easy as it is with the Intel audio device. Regards, Ralf
