hello thank you , i eventually tried to follow the instructions on this page https://wiki.gentoo.org/wiki/Multiseatto avoid system wide pulseaudio on my multiseat. So i load modules (driver) statically and then i have no problem to give each seat its hdmi output and webcam (audio input).The problem is that my webcams are only detected by pulseaudio but not seen in pavucontrol as input devices , ... apparantly the webcams need to be automatically loaded with udev to be operational, but of course if i use the automatic audio drivers loading then i cant avoid that the first loging seat  takes the two  hdmi "sound cards" and the second one has no more "hdmi sound" access : hdmi seen unplugged! i'm wondering if there is something wrong with my manual loading of the webcams, for instance this one load-module module-alsa-card device_id="3" name="pci-0000:00:1d.0-usb-0:1.7:1.2" card_name="alsa_card.usb-046d_0825_D568E1A0-02-U0x46d0x825" tsched=yes ignore_dB=no i took device id, cardname and name from a pactlist: Card #2    Name : alsa_card.usb-046d_0825_D568E1A0-02-U0x46d0x825    Driver : module-alsa-card.c    Proprietary Module  : 7    Properties :        alsa.card = "3"        alsa.card_name = "USB Device 0x46d:0x825"        alsa.long_card_name = "USB Device 0x46d:0x825 at usb-0000:00:1d.0-1.7, high speed"        alsa.driver_name = "snd_usb_audio"        device.bus_path = "pci-0000:00:1d.0-usb-0:1.7:1.2"        sysfs.path = "/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.2/sound/card3"        udev.id = "usb-046d_0825_D568E1A0-02-U0x46d0x825"        device.bus = "usb"        device.vendor.id = "046d"        device.vendor.name = "Logitech, Inc."        device.product.id = "0825"        device.product.name = "Webcam C270"        device.serial = "046d_0825_D568E1A0"        device.form_factor = "webcam"        device.string = "3"        device.description = "Webcam C270"        device.icon_name = "camera-web-usb"    Profils :        input:analog-mono: Mono analogique Input (sinks: 0, sources: 1, priority: 1, available: yes)        off: �teint (sinks: 0, sources: 0, priority: 0, available: yes)    Profil actif : input:analog-mono    Ports :        analog-input-mic: Microphone (priority: 8700, latency offset: 0 usec)            Properties:                device.icon_name = "audio-input-microphone"            Part of profile(s): input:analog-mono is there a missing or bad options ? something else to do to get fully working webcams ? thank you in advance regards, F H-C Le Jeudi 26 mai 2016 14h00, "pulseaudio-discuss-request at lists.freedesktop.org" <pulseaudio-discuss-request at lists.freedesktop.org> a écrit : Send pulseaudio-discuss mailing list submissions to    pulseaudio-discuss at lists.freedesktop.org To subscribe or unsubscribe via the World Wide Web, visit    https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss or, via email, send a message with subject or body 'help' to    pulseaudio-discuss-request at lists.freedesktop.org You can reach the person managing the list at    pulseaudio-discuss-owner at lists.freedesktop.org When replying, please edit your Subject line so it is more specific than "Re: Contents of pulseaudio-discuss digest..."

I'm sure there is some alternative. I doubt that it's much better than just using the system mode, however.

We haven't changed anything in this regard. The distribution is responsible for creating users and groups in the system. I suppose you can create them yourself too, though. When pulseudio runs in the system mode, it switches from root to user "pulse". That (and only that) is what the "pulse" user and group are for. The "pulse-access" group is for authorizing users to use pulseaudio, so you have to add your users to that group. -- Tanu ------------------------------ Message: 2 Date: Wed, 25 May 2016 22:26:42 +1200 From: Aidan Gauland <aidalgol@xxxxxxxxxxxx> To: pulseaudio-discuss at lists.freedesktop.org Cc: Aidan Gauland <aidalgol at fastmail.net> Subject: [PATCH] Don't set font-size on widgets Message-ID: <1464172002-15340-1-git-send-email-aidalgol at fastmail.net> Setting the font-size CSS property on a widget overrides the system font-size, and since qpaeq provides no mechanism for setting the application's font-size, we should not do this.
