Re: [pulseaudio-discuss] several seconds delay while playing video with timer-based audio scheduling enabled

The abnormal phenomenon disappeared after turn it off. I use 2.6.37 kernel and 0.9.22 pulseaudio version. As suggestions (http://0pointer.de/blog/projects/pulse-glitch-free.html) the pulseaudio's glitch-free works on newest Alsa/Kernel/Pulseaudio, newest everything. After some google search, there's no obvious finding about similar issues. Meanwhile i guess the official release of glitch-free must be verified about tsched feature, so it's not a bug but a usage mistake,such as some config file wrong for my platform. So if anyone had meet same issue or could you provide some suggestions, that would be appreciated much. What video player is being used? It is perhaps making some really dumb assumptions about things and thus breaking (and using too much power too!) It's Meego default player meego-qml-launcher. Maybe wrong here. Qml-launcher is only one app launcher, the exact app name is meego-app-video, it's one QML based application. --xingchao Col -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mageia Contributor [http://www.mageia.org/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/] ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

This was just introduced for debugging and should not have been in the
final commit. Won't make a difference at the moment since this function
is used as a pointer, but removing this in case we change this in the

Hello, 'Twas brillig, and Lin, Mengdong at 10/05/11 08:37 did gyre and gimble: How pulseaudio support autospawn? After pulse audio daemon is killed manually, how it will be executed automatically? How can it know some client is attempts to connect to it? Could someone introduce its internal implementation? This is performed automatically by libpulse. All pulseaudio client appliations (be them native applications supporting PA directly or an ALSA application using the alsa-pulse plugin) use libpulse. It has code that tries to connect to the daemon, and if that connection fails it will automatically attempt to spawn a pulseaudio daemon and then connect to it. There are some exceptions to this e.g. * when the client application is trying to connect to a remote address. * when autospawn=no is set in client.conf * possibly a couple more I forget off the top of my head :D I got a explanation of autospawn: “ if the daemon is not running when the first client attempts to connect, it will be executed automatically” (From http://www.linux-archive.org/ubuntu-development/246411-notable-changes-jauntys-pulseaudio.html) But I hope someone can give more detail.

[pulseaudio-discuss] [PATCHv3 0/4] Read and store UCM data as proplist
This is the third version of the Pulseaudio and UCM integration. This set of patches cover adding ucm data to proplist, adding a ucm API to get and set data to proplist, and lets module-alsa-card scan ucm data when the card is probed. Another set of patches dealing with jack module detection will be sent separately. Changes from v2: - clean up and add documentation to some structures and functions. - changed commit subjects to better reflect changes in code. - used pa_log_debug() instead of pa_log() to avoid saturating the output. ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

From: Margarita Olaya Cabrera m...@slimlogic.co.uk
This patch adds ALSA UCM (Use Case Manager) support to module alsa card.
It checks if UCM is available for each card and if found it uses the profiles
generated with ucm data.
Using a udev-rule user can decide if UCM will be used or not,
Depending on the status of USE_UCM property, a flag is passed as
module argument to module-alsa-card.

[pulseaudio-discuss] [PATCHv3 3/4] alsa: Add UCM API for managing UCM propoerties
From: Margarita Olaya Cabrera m...@slimlogic.co.uk
The UCM stores the mixer settings per use case in configuration files, these
files contains information such:
- list of use case verbs per card or machine
- supported devices per use case verb
- use case sink device
- use case source device
- hardware playback volume control id (per use case verb and device)
- hardware playback mute switch id
- hardware capture volume control id
- hardware capture mute switch id
The new ucm data structures are used to store that info so it can be used by
pulseaudio.
This patch also adds ALSA UCM (Use Case Manager) calls.
It checks if UCM is available for each card and if found, scans each UCM
property verb, device and modifier for the card. It then then creates
mappings for each supported UCM verb and device so that changes to the
pulseaudio profile cause corresponding changes to the UCM verb and
device for the card.

[pulseaudio-discuss] Is it possible to compress pulseaudio's network streams?
Dear list, I've been using Pulseaudio over the network for a while. When my laptop is docked it works pretty well through the wired connection, but when I go wireless sound gets choppy. This situation makes the whole network functionality almost non-sense for me as I could attach my usb sound card directly to my dock station (with 5.1 speakers). Checking the traffic I get an around 4mb/s sustained flow which I guess is too high for my unreliable wireless network. I've googled quite a lot and I haven't found any real effective solution to this issue. I guess the better solution would be to compress these streams in order to reduce bandwidth requirements. Is it possible to do this in pulseaudio. Are there any plans of implementing some solution for this situation? Which are the most important parameters I should try to tune apart from default-fragments and default-fragment-size-msec?
