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: Éteint (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

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

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.

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.
This commit also removes the font-size property from commented-out calls to
setStyleSheet() so that if these are ever reinstated, this behaviour is
not reintroduced.
