I should probably give more details about the machines and the network
now. I've three machines with PulseAudio on: viper, duke and atom.
viper is a desktop connected to the switch running F8 that was actually
a result of updating from Rawhide (as a side note: I'm also experiencing
weirdness on this machine where I'm not seeing corresponding updates in
pavucontrol whenever I add virtual output devices (see my other
message)). Network driver: forcedeth
duke is a new notebook with modern specs connected also to the switch
running F8. Network driver: forcedeth
atom is an old laptop (Pentium ///) connected via a wireless router,
which, in turn, is connected via a powerline bridge to the switch. Also
running updated F8. Network driver: ath_pci
On all three machines, I've yum updated them fairly recently and are
running PA 0.9.8 from rawhide (as well as corresponding utils).
I ran "avahi-browse -at | sort" from all three machines and got the ff.:
+ eth0 IPv4 atom [00:13:46:21:61:6a] _workstation._tcp local
+ eth0 IPv4 atom _ssh._tcp local
+ eth0 IPv4 duke [00:16:d3:f1:57:33] _workstation._tcp local
+ eth0 IPv4 duke _ssh._tcp local
+ eth0 IPv4 legacy [00:16:e6:1e:a0:64] _workstation._tcp local
+ eth0 IPv4 richip at atom: ALSA PCM on front:0 (Maestro3) via DMA _pulse-sink._tcp local
+ eth0 IPv4 richip at atom: ALSA PCM on front:0 (Maestro3) via DMA _pulse-source._tcp local
+ eth0 IPv4 richip at atom _pulse-server._tcp local
+ eth0 IPv4 richip at duke: ALSA PCM on front:0 (CONEXANT Analog) via DMA _pulse-sink._tcp local
+ eth0 IPv4 richip at duke: ALSA PCM on front:0 (CONEXANT Analog) via DMA _pulse-source._tcp local
+ eth0 IPv4 richip at duke _pulse-server._tcp local
+ eth0 IPv4 Richi Plana _h323._tcp local
+ eth0 IPv4 Richi Plana _sip._udp local
+ eth0 IPv4 richip's public files on viper _webdav._tcp local
+ eth0 IPv4 SFTP File Transfer on legacy _sftp-ssh._tcp local
+ eth0 IPv4 viper [00:0f:ea:73:b4:01] _workstation._tcp local
+ eth0 IPv4 viper _ssh._tcp local
The only difference was that on atom, instead of e.g.
"_workstation._tcp" showing, it would display "Workstation" (and I've no
idea why since they're the same command-line arguments. Only difference
is that it's using i386 binaries as opposed to x86_64 on the others). On
all three machines, I'm not seeing remote devices in the "_Output
Devices" tab on pavucontrol (which is set to "S_how" "All Output
I seriously think that viper (which was updated from f7-rawhide) is
seriously broken. I'm thinking of installing from scratch, but I'll
refrain from doing so in case someone wants forensic clues. Otherwise,
I'll re-install ASAP.
