Re: [pulseaudio-discuss] [PATCH pavucontrol] mainwindow: Show the availability of the ports and profiles.
The ports variable contains all ports of a card. Here I think you add all output ports of a card to all sinks of the card and all input ports to all sources. That's not right, a sink may have only a subset of the card's output ports assigned to it. The plugged in and unplugged strings should probably be translatable. (Same for the profile code.) Good catch. I got myself thinking that I could generalize the solution a little bit but it seems that we can't figure out which port belongs where just from pa_card_port_info. I think profiles should be plugged in if any port is available. i have doubt about it the profile is not available when the jack available state of the port is NO but all profiles have passed the open pcm test. this mean that some port does not have jack detect capability (e.g. some nvidia hdmi , spdif, all pci sound cards and onboard ac97 sound card, ) ___ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss

Audio1 is reserved (the service exists), but the object to request a
release for Audio1 doesn't exist. Getting to this state was actually
quite easy:
1. Start into KDE (pulse is set up as normal for Fedora and autostarted).
2. Start d-feet, you may catch the ReserveDevice1 services before they
disappear, but wait till they do.
3. Open the KDE audio setup dialogue and test playback, this causes
pulse to lock the capture device (hw:0 here) and the playback device
(hw:1).
4. Look at the 'reserved' services. Audio1 is reserved, but can't be
released because there's no object to provide the method.

It seems rd_acquire can get called while pulse still has the service
name (how? don't know. I've tried a return 0 there, but the object
path has already been unregistered at that point). Currently that
means it unregisters the filter handler and the object path for
releasedevice1, turning the service into a zombie until pulse is
killed. I've tried fixing this by changing the way d-owning is used,
but anything but the current setup seems to get stuck in a loop
between rd_callback, the filter_handler in reserve.c and rd_release,
possibly because unregistering the service triggers the filter_handler
with namelost somehow. Anyway, thou shalt check for possible return
values.

This means that you have not plugged your microphone in. If it's still available: no when your mic is plugged in, it is very likely an ALSA bug. module-switch-on-port-available is the module that switches away from unavailable ports. Okay, following up with Raymond Yau, who asks me my alsa-info.sh -- If yes, how can I work around this? If no, any other idea? Any solution putting Microphone first will do, I don't care the least about Internal Microphone. In the same files you just edited, you can also comment out the Jack sections to stop PulseAudio from picking up any detection. Commenting didn't work, but I added 'state.plugged = yes' and 'state.unplugged = yes' to the [Jack Mic] section for the input I want. Now it is always detected as plugged and the priority thing works :) Thanks! -- Ronan Jouchet ___ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
Re: [pulseaudio-discuss] Low latency
Not sure what you mean with sink and ring buffer. When mixing, data goes from the sink-input / client-server buffer into the DMA buffer directly. Please look at protocol-native.c. I am not sure why there is this division of latency in two, for low-latency you can probably decrease the client buffer some. /* So, the user asked us to adjust the latency of the stream * buffer according to the what the sink can provide. The * tlength passed in shall be the overall latency. Roughly * half the latency will be spent on the hw buffer, the other * half of it in the async buffer queue we maintain for each * client. In between we'll have a safety space of size * 2*minreq. Why the 2*minreq? When the hw buffer is completely * empty and needs to be filled, then our buffer must have * enough data to fulfill this request immediately and thus * have at least the same tlength as the size of the hw * buffer.

Has anyone tried the changes we pushed recently at the kernel level to properly handle the ring buffer pointer and delay? I believe some of the underruns may be due to the ~1ms inaccuracy that we had before these changes. If your driver is already giving you a 25% precision error no wonder things are broken? Right now we have bigger issues, such as why nobody is responding to messages such as this one [1] :-( Quite frankly I did not understand the problem you are facing and what these measurements show. Maybe you're on to something but it's hard to provide feedback here. ___ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
