Currently I am trying standard headset with mic (3.5 mm) and not USB headset. on ubuntu 10.10 desktop -module-udev-detect is loaded -I am trying out use-case of headset plug/unplug , when music is playing on totem player the audio is getting routed to headset automatically when HS is plugged-in. (which is expected :-) ) -here I am expecting to see an new sink device in the list-sinks which is not happening? on device with 2.6.35 kernel and PA 0.9.21 - module-udev-detect is loaded - audio is NOT getting routed to headset automatically when HS is plugged-in, while playing music through gst-launch ? Not sure why ? - here also I am expecting to see an new sink device in the list-sinks which is not happening? here is the list-sinks output (of ubuntu10.10) it remains same irrespective of doing headset plugin/plugout : 1 sink(s) available. * index: 0 name: <alsa_output.pci-0000_00_1b.0.analog-stereo> driver: <module-alsa-card.c> flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY DYNAMIC_LATENCY state: SUSPENDED suspend cause: IDLE priority: 9959 volume: 0: 65% 1: 65% 0: -11.41 dB 1: -11.41 dB balance 0.00 base volume: 100% 0.00 dB volume steps: 65537 muted: no current latency: 0.00 ms max request: 0 KiB max rewind: 0 KiB monitor source: 0 sample spec: s16le 2ch 44100Hz channel map: front-left,front-right Stereo used by: 0 linked by: 0 configured latency: 0.00 ms; range is 0.50 .. 1999.82 ms card: 0 <alsa_card.pci-0000_00_1b.0> module: 4 properties: alsa.resolution_bits = "16" device.api = "alsa" device.class = "sound" alsa.class = "generic" alsa.subclass = "generic-mix" <a href="http://alsa.name">alsa.name</a> = "AD198x Analog" <a href="http://alsa.id">alsa.id</a> = "AD198x Analog" alsa.subdevice = "0" alsa.subdevice_name = "subdevice #0" alsa.device = "0" alsa.card = "0" alsa.card_name = "HDA Intel" alsa.long_card_name = "HDA Intel at 0xdfdfc000 irq 43" alsa.driver_name = "snd_hda_intel" device.bus_path = "pci-0000:00:1b.0" sysfs.path = "/devices/pci0000:00/0000:00:1b.0/sound/card0" device.bus = "pci" <a href="http://device.vendor.id">device.vendor.id</a> = "8086" <a href="http://device.vendor.name">device.vendor.name</a> = "Intel Corporation" <a href="http://device.product.id">device.product.id</a> = "27d8" <a href="http://device.product.name">device.product.name</a> = "N10/ICH 7 Family High Definition Audio Controller" device.form_factor = "internal" device.string = "front:0" device.buffering.buffer_size = "352768" device.buffering.fragment_size = "176384" device.access_mode = "mmap+timer" <a href="http://device.profile.name">device.profile.name</a> = "analog-stereo" device.profile.description = "Analog Stereo" device.description = "Internal Audio Analog Stereo" alsa.mixer_name = "Analog Devices AD1984" alsa.components = "HDA:11d41984,10280220,00100400" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" ports: analog-output: Analog Output (priority 9900) analog-output-headphones: Analog Headphones (priority 9000) active port: <analog-output> Device >>> list-sinks 1 sink(s) available. * index: 0 name: <alsa_output.hw_0_0> driver: <module-alsa-sink.c> flags: HARDWARE DECIBEL_VOLUME LATENCY FLAT_VOLUME DYNAMIC_LATENCY state: SUSPENDED suspend cause: IDLE priority: 9000 volume: 0: 100% 1: 100% 0: 0.00 dB 1: 0.00 dB balance 0.00 base volume: 100% 0.00 dB volume steps: 65537 muted: no current latency: 0.00 ms max request: 127 KiB max rewind: 127 KiB monitor source: 0 sample spec: s16le 2ch 44100Hz channel map: front-left,front-right Stereo used by: 0 linked by: 0 configured latency: 0.00 ms; range is 0.50 .. 742.31 ms module: 4 properties: alsa.resolution_bits = "16" device.api = "alsa" device.class = "sound" alsa.class = "generic" alsa.subclass = "generic-mix" <a href="http://alsa.name">alsa.name</a> = "" <a href="http://alsa.id">alsa.id</a> = "McBSP2-STDac cpcap stdac-0" alsa.subdevice = "0" alsa.subdevice_name = "subdevice #0" alsa.device = "0" alsa.card = "0" alsa.card_name = "motsnd" alsa.long_card_name = "Motorola MAPPHONE" device.string = "hw:0,0" device.buffering.buffer_size = "130944" device.buffering.fragment_size = "65472" device.access_mode = "mmap+timer" device.description = "motsnd" device.icon_name = "audio-card" any idea, what went wrong ?

That said you should still remove that line as it's not needed. I actually clarified the wording on the wiki page that lead you to add this line as another user on IRC got caught out by it too. Hopefully it's clearer now. So, the problem of your USB not showing up is presumably still there.. If udev is working correctly now, then I'd run PA manually via pulseaudio -vvvvv and look for the debug that should spew out when you do the plug/unplug. My initial guess at the problem would be one of permissions. i.e. your user may not be allowed to access this new device node that is created. In a typical desktop env, udev will use udev-acl to give your user permission via an ACL on the device node. PA will only add a sink/source if your user actually has permission to open the device. This last bit is just a guess tho'. Hope it helps. <div><div></div><div class="h5"> Col -- Colin Guthrie gmane(at)<a href="http://colin.guthr.ie" target="_blank">colin.guthr.ie</a> <a href="http://colin.guthr.ie/" target="_blank">http://colin.guthr.ie/</a> Day Job: Tribalogic Limited [<a href="http://www.tribalogic.net/" target="_blank">http://www.tribalogic.net/</a>] Open Source: Mageia Contributor [<a href="http://www.mageia.org/" target="_blank">http://www.mageia.org/</a>] PulseAudio Hacker [<a href="http://www.pulseaudio.org/" target="_blank">http://www.pulseaudio.org/</a>] Trac Hacker [<a href="http://trac.edgewall.org/" target="_blank">http://trac.edgewall.org/</a>] _______________________________________________ pulseaudio-discuss mailing list <a href="mailto:pulseaudio-discuss@lists.freedesktop.org">pulseaudio-discuss@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss" target="_blank">http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss</a> </div></div></blockquote></div>
