[Alsa-user] ALSA dsnoop and RAT (Robust Audio Tool)
Hello all!
I got a RAT (Robust Audio Tool) application and try to make works many
instances of it properly. There is a my configuration:
http://www.alsa-project.org/db/?f=e6185615279fc6dec5bbc81336ec6d346b9d0a9d(its
default)
By default I can start two or more instances of RAT, but sound from
microphone is ugly (have a lot of jamming and interference) in this
application (in arecord and aplay sound is perfect). I waste some time and
found a problem. Problem is RAT cannot work properly with dsnoop plugin. I
go to the my card config /usr/share/alsa/cards/HDA-Intel.conf and just
change dsnoop plugin to hw:
from
# default with dmix+softvol dsnoop
HDA-Intel.pcm.default {
...
type asym
playback.pcm {
...
}
capture.pcm {
type plug
slave.pcm {
type softvol
slave.pcm {
@func concat
strings [ dsnoop: $CARD ]
}
...
}
...
}
hint.device 0
}
to
# default with dmix+softvol dsnoop
HDA-Intel.pcm.default {
...
type asym
playback.pcm {
...
}
capture.pcm {
type plug
slave.pcm {
type softvol
slave.pcm {
@func concat
strings [ hw: $CARD ]
}
...
}
...
}
hint.device 0
}
Sound from mic become perfect everywhere but I cant start many instances of
RAT any more. Looks like without dsnoop capture device become used monopoly
by first instance of RAT so second instances of application cannot use it.
My question is how to make works many instances of this application (or
share default capture device if you like) without dsnoop. dshare plugin
cannot work with capture so I looking for another way.
Also I try to change default settings for dsnoop many times, it helps only
time for time and not for long but I need stable solution. Sorry for my
English :)

Re: [Alsa-user] CA0110-IBG, ac3 spdif capture and analog playback
Please note, I am no expert. But I bought a computer with an SB X-Fi Xtreme Audio PCIe card. It seems that the card is currently unsupported by ALSA and I was not able to find any way to work around the problem. Other cards that are named SB X-Fi are supported so it's a little confusing to search for solutions. I ended up getting a USB external card and I've been happy since. Good luck.

BTW this trick is not work for rate 48000 . When I set defaults.pcm.dmix.!rate 48000 in ~/.asoundrc and in RAT 48000 I still have interference what sounds like random bleeps when I listen what I talk to microphone. 2010/3/3 Paul Menzel paulepan...@users.sourceforge.net also if you are just running one RAT instance? Yes with one instance of RAT problem still have. Did you try `arecord` with the dsnoop device? Actually I test recording with Audacity. When microphone sound via RAT have interference I record my voice in Audacity and sound in recorded track was fine. Did you try to use a sound server like PulseAudio? Yes! It great server. But RAT have a ugly memory leak and 100% usage CPU when use PulseAudio device. I cannot find how to fix it So I just turn off PulseAudio. Could you please rephrase this sentence. I did not get its meaning? What did you change and what were the differences. I was try to edit default settings for dsnoop in /usr/share/alsa/pcm/dsnoop.conf I add channels 2 and bindings.0 0 to make a mono and also I change format $FORMAT to format S16_LE.

Re: [Alsa-user] Intel HDA: HDMI audio on i945GT
Great. Just for my interest to know about tried/tested HTPC setups. Did you put the components you used somewhere? I'm not sure where these things are listed it was an old purchase stuck into an existing setup, to be honest I didn't think I was ever going to use it again as I believe the NVidia ION is now a popular choice due to the HD acceleration etc. The only reason I got this out again is because the original motherboard has a broken SPDIF socket, it was an AOpen which used a very flimsy plug to connect SPDIF through a specialised 3.5mm audio socket. In this instance I'm only using the onboard hardware of the ABIT iL-90MV so that really covers it all anyway. Was it hard to setup? Or did you just follow [1]? Again because this was an old setup most of the config for the IEC was on the backend server and some of it did require a lot of googling to find out at the time, which was probably a couple of years ago now. But mainly it's just the appropriate string to stuff into the mythtv setup (the original IEC settings still work). Other than that the default gentoo build process worked without too many issues I dont recall doing anything special to setup sound. I have to say, that I do not if it will work. But I am pretty sure that chances are small that it will work right away. What prevents you from just trying it? I've already tried, if you refer to the aplay -l listing there is no HDMI connector available to use. If it does not work you should also try the latest releases first. I've given that a go and unfortunately it doesn't work. What I can say is that I can trick the system into giving me an HDMI connector by patching the code (patch_intelhdmi.c) but this of course doesn't give me a useable device. It does however make me believe that the issue lies with the drivers and not with something I've forgot to do? The codec is presented as 0x10ec0882 (I believe that is a Realtek 882), the hardware is listed as follows using lspci. 00:1b.0 Audio device [0403]: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller [8086:27d8] (rev 02) However afaik HDMI audio is sent using the SDVO interface of the Intel graphics adapter and probably has little to do with the actual sound hardware at all. It just needs an Alsa interface so other programs can interface with it in the normal way. I believe the process is that the video driver will need to detect the relevant SDVO output firstly as HDMI and further as HDMI audio capable. I believe that there is also a mechanism for reconfiguring the audio outputs at this point. I've done some logging and I don't believe that the video driver even detects that I have an HDMI connection. If I hard coded the is_hdmi setting and SDVO_AUDIO_ENABLE there is still no change so I believe whatever is going on is more complex than that. The problem is I'm not entirely sure who to ask first, starting here seemed like a good idea as Audio therefore Alsa. However it is possible that until the video driver is setup to handle the 945GT chipset no progress can be made. Really at this point I think I need some advice from the developers as working out how the linking between the video driver and the audio driver operates may be difficult. Thanks for your assistance and if you have any other ideas to follow up on I may give them a try. Will -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
