[pulseaudio-discuss] specifying ALSA mixer control
Hi,
My audio device has an IEC958 output as well as analog out. I set up
two module-alsa-sink's so that i can direct streams to either output,
but I found that I couldn't control the volume of each sink
independently. I was able to use asound.conf to create a softvol
control for the digital out. However, module-alsa-sink doesn't have
any way to select a particular mixer control. Since both pcms are
part of the same card they both end up using the Master control.
The attached patch adds an argument called control to the ALSA sink
module. If this argument is specified it tries to use that control.
Otherwise it uses the current method of selecting Master, with PCM as
a fallback.
Best,
Kyle

While I could be wrong (as I don't have much hardware to test despite writing the above feature in pavucontrol!), I don't think pulse probes for dual simultaneous outputs at present. As you can see in that screenshot the analog and digial outputs are exclusive... So while it's a step towards not requiring custom setups, it's not completely there yet. AFAIK this really depends on hardware. Above screenshot is from my laptop (Centrino 2, Intel HDA on Connexant chip), I once saw this dialog on computer with EMU10K card. The list was bigger than screen and there were various combinations. So, if the card supports simultanous output to SPDIF and analog, there will be two ink available. This is how I undestand profiles :) Another funny thing, my laptop has only analog jack for headphones. Somehow chipset capabilities (or non existand dock capabilities) are exposed, not the physical outputs. -- Tomasz Torcz Never underestimate the bandwidth of a station xmpp: zdzich...@chrome.plwagon filled with backup tapes. -- Jim Gray ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss
[pulseaudio-discuss] Description for virtual sinks
Is there any particular reason that it is not possible to set the description when making a sink with module-remap-sink (or his friends module-combine, module-tunnel-sink, etc.)? It seems that the description is always derived from the master sink, but I would like to customize it, because this is the name that is shown in interfaces like pavucontrol.

This is how I undestand profiles :) The problem is not that I had to manually specify two sinks in the config file. I don't mind doing that. The problem is that the only way for me to independently control the volume of the SPDIF was to create a custom mixer control using softvol. So I needed a way to select this as the mixer for one of the sinks. I tried installing the latest git sources on my Ubuntu Jaunty box but it just broke sound in all my applications. For my own purposes, I'm going to need to start with the Ubuntu-patched 0.9.14. However, if you are willing to accept this patch I will forward port it so that it applies to the latest sources. It's a completely harmless change, so why not apply it? Thanks, Kyle Another funny thing, my laptop has only analog jack for headphones.
