#926: usb soundcard does not work reliably in pulseaudio, but works otherwise ---------------------+------------------------------------------------------ Reporter: martin | Owner: lennart Type: defect | Status: new Milestone: | Component: daemon Resolution: | Keywords: ---------------------+------------------------------------------------------
Comment(by coling): For really large output please attach rather than paste inline (tho' thanks for getting the right WikiFormatting :)) as it makes the body of the bug easier to read. OK, so here is the important bit (/me ignores own advice above): {{{ 3 card(s) available. index: 0 name: <alsa_card.usb-M-Audio_Sonica_Theater-00-Theater> driver: <module-alsa-card.c> owner module: 4 properties: alsa.card = "2" alsa.card_name = "Sonica Theater" alsa.long_card_name = "M-Audio Sonica Theater at usb-0000:00:1d.1-1, full speed" alsa.driver_name = "snd_usb_audio" device.bus_path = "pci-0000:00:1d.1-usb-0:1:1.0" sysfs.path = "/devices/pci0000:00/0000:00:1d.1/usb3/3-1/3-1:1.0/sound/card2" udev.id = "usb-M-Audio_Sonica_Theater-00-Theater" device.bus = "usb" device.vendor.id = "0763" device.vendor.name = "Midiman" device.product.id = "2007" device.product.name = "M-Audio Sonica Theater" device.serial = "M-Audio_Sonica_Theater" device.string = "2" device.description = "M-Audio Sonica Theater" module-udev-detect.discovered = "1" device.icon_name = "audio-card-usb" profiles: output:analog-stereo: Analog Stereo Output (priority 6000) output:analog-stereo+input:analog-stereo: Analog Stereo Duplex (priority 6060) output:analog-stereo+input:iec958-stereo: Analog Stereo Output + Digital Stereo (IEC958) Input (priority 6055) output:analog-surround-40: Analog Surround 4.0 Output (priority 700) output:analog-surround-40+input:analog-stereo: Analog Surround 4.0 Output + Analog Stereo Input (priority 760) output:analog-surround-40+input:iec958-stereo: Analog Surround 4.0 Output + Digital Stereo (IEC958) Input (priority 755) output:analog-surround-41: Analog Surround 4.1 Output (priority 800) output:analog-surround-41+input:analog-stereo: Analog Surround 4.1 Output + Analog Stereo Input (priority 860) output:analog-surround-41+input:iec958-stereo: Analog Surround 4.1 Output + Digital Stereo (IEC958) Input (priority 855) off: Aus (priority 0) active profile: <output:analog-stereo+input:analog-stereo> index: 1 name: <alsa_card.pci-0000_00_1f.5> driver: <module-alsa-card.c> owner module: 5 properties: alsa.card = "0" alsa.card_name = "Intel 82801DB-ICH4" alsa.long_card_name = "Intel 82801DB-ICH4 with AD1981B at irq 11" alsa.driver_name = "snd_intel8x0" device.bus_path = "pci-0000:00:1f.5" sysfs.path = "/devices/pci0000:00/0000:00:1f.5/sound/card0" device.bus = "pci" device.vendor.id = "8086" device.vendor.name = "Intel Corporation" device.product.id = "24c5" device.product.name = "82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller" device.form_factor = "internal" device.string = "0" device.description = "Internes Audio" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" profiles: output:analog-stereo: Analog Stereo Output (priority 6000) output:analog-stereo+input:analog-stereo: Analog Stereo Duplex (priority 6060) input:analog-stereo: Analog Stereo Input (priority 60) off: Aus (priority 0) active profile: <output:analog-stereo+input:analog-stereo> sinks: alsa_output.pci-0000_00_1f.5.analog-stereo/#0: Internes Audio Analog Stereo sources: alsa_output.pci-0000_00_1f.5.analog-stereo.monitor/#0: Monitor of Internes Audio Analog Stereo alsa_input.pci-0000_00_1f.5.analog-stereo/#1: Internes Audio Analog Stereo index: 2 name: <alsa_card.pci-0000_00_1f.6> driver: <module-alsa-card.c> owner module: 6 properties: alsa.card = "1" alsa.card_name = "Intel 82801DB-ICH4 Modem" alsa.long_card_name = "Intel 82801DB-ICH4 Modem at irq 11" alsa.driver_name = "snd_intel8x0m" device.bus_path = "pci-0000:00:1f.6" sysfs.path = "/devices/pci0000:00/0000:00:1f.6/sound/card1" device.bus = "pci" device.vendor.id = "8086" device.vendor.name = "Intel Corporation" device.product.id = "24c6" device.product.name = "82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Modem Controller" device.class = "modem" device.string = "1" device.description = "Modem" module-udev-detect.discovered = "1" device.icon_name = "modem-pci" profiles: output:analog-mono: Analog Mono Output (priority 100) output:analog-mono+input:analog-mono: Analog Mono Duplex (priority 101) input:analog-mono: Analog Mono Input (priority 1) off: Aus (priority 0) active profile: <output:analog-mono+input:analog-mono> }}} As you can see we have detected 3 "cards". One is your USB, the other is your internal card and third appears to be a modem of some kind. The internal card appears to be working correctly, as you can see from the output above, it has selected and active profile as follows: {{{ active profile: <output:analog-stereo+input:analog-stereo> sinks: alsa_output.pci-0000_00_1f.5.analog-stereo/#0: Internes Audio Analog Stereo sources: alsa_output.pci-0000_00_1f.5.analog-stereo.monitor/#0: Monitor of Internes Audio Analog Stereo alsa_input.pci-0000_00_1f.5.analog-stereo/#1: Internes Audio Analog Stereo }}} So this profile enables the following sinks/sources. However, if you look at both your other cards you'll see that neither of them has any sinks/sources, despite you choosing a profile that should enable them. For the modem this is not super surprising. Some lower level daemon on your system may be hogging the modem device for good reason, so we should likely discount that. But for the USB there are essentially only a handful of reasons that this can go wrong. 1. Some other application was hogging the USB device when the profile was activated (i.e. when it was plugged in). You can check this via "fuser -v /dev/snd/*" 1. There is a race condition on your system and the sound card announced itself via udev before it was actually ready. Thus PA tried to open it before things were really stable. You can test this by changing the active profile to Off then back to the one you want (use the Configuration tab of pavucontrol). If this makes the Sinks/Sources appear, then this is a candidate for the problem. You can check the output above via "pacmd list- cards" for a slightly shorter dump, but you can also just look on pavucontrol's Output Devices tab. 1. There is a problem connection to DBus. This will only happen when PA has somehow lost it's connection to DBus and you subsequently plug in the device. If this happens, then the device reservation protocol cannot operate and we cannot "claim" the device. This is a mechanism for us to be a nice citizen and play with other applications that want direct h/w access (e.g. JACK). You can test this quite easily. Just change your Internal card's profile to Off and then back again. If it's sinks/sources suddenly disappear, then this is a likely cause. You can also run qdbusviewer (or similar) and make sure that pulseaudio appears on the session bus. If it does not then this is likely the problem. I hope I've given you a few things to check on and it will help identify which component has the problem. -- Ticket URL: <http://pulseaudio.org/ticket/926#comment:6> PulseAudio <http://pulseaudio.org/> The PulseAudio Sound Server _______________________________________________ pulseaudio-tickets mailing list pulseaudio-tickets@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-tickets
