Jack and amixer volume control problems

Rate this Message:
Hi folks,
i have "jack" and "ALSA" installed on my SuSE 11 Linux 2.6 workstation together with a Aureon 7.1 PCI sound card. I can play musik with "mpd" via "jack" but cannot control the volume with means of "alsamixer" nor "amixer". I can see the associated volume control slider for all channels but only "Master" has an effect. When i play the musik direcly to the defined "ALSA PCM output" everything is working fine! How can I control the volume when using "jack" and "ALSA". Any help is welcome:-) Best Regards, Torsten ________________________________________________________________ Neu: WEB.DE Doppel-FLAT mit Internet-Flatrate + Telefon-Flatrate für nur 19,99 Euro/mtl.!* http://produkte.web.de/go/02/ _______________________________________________ Jack-Devel mailing list Jack-Devel@... http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org |

For Envy24 cards there is, as for other cards too, a mixer just for This/those cards. You might want to take a look if there's a mixer just for your card or the chipset of your card. _______________________________________________ Jack-Devel mailing list Jack-Devel@... http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org |

PS:
*lol* The world wide web says your card is using a ICE1724, this is an Envy24 chip, I only wonder that your card allegedly isn't able to do 24/96, anyway ... you need to run envy24control and for Suse this might be in the package alsa-tools.

PPS:
If you still need information, because I'm mistaken, please as superuser run hwinfo --sound and post the output here. I guess Suse installs hwinfo as default, Suse did in the past.

Sorry, I was mistaken, the chip 1712 is Envy24 and the 1724 is something
different. Torsten Krieger wrote: > Hi folks, > > i have "jack" and "ALSA" installed on my SuSE 11 Linux 2.6 workstation together with a Aureon 7.1 PCI sound card.

A last mail (note) ... for op-amps the numbers on the microchips very
often say how many op-amps for a special type of op-amp are in the microchip, maybe it's similar for this AD/DA stuff, the ICE1724 might be an ICE 1712.

The ICE1712 has nothing to do with AD/DA or op amps. It is not the same as ICE1724 either.

I didn't wrote that it's the converter or that it is an op-amp. It was just a tip for what I would Google search if I would search a Linux mixer for an ICE1724 card. _______________________________________________ Jack-Devel mailing list Jack-Devel@... http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org |

I DON'T KNOW, I JUST TRY TO HELP ;) what ever the ICE1724 chip or chipset might be, I would search the ALSA-dev mailing list archive: "The mailing list for ALSA developers. /[open, unmoderated for subscribers, moderated for others]/ If you would like to work on the driver, library or an ALSA application subscribe to alsa-devel here <http://mailman.alsa-project.org/mailman/listinfo/alsa-devel>. * alsa-devel archive at mailman.alsa-project.org <http://mailman.alsa-project.org/pipermail/alsa-devel/> * alsa-devel archive at gmane.org <http://news.gmane.org/gmane.linux.alsa.devel> * alsa-devel archive at mail-archive.com <http://www.mail-archive.com/alsa-devel%40lists.sourceforge.net> * alsa-devel archive at geocrawler <http://www.geocrawler.com/lists/3/SourceForge/12349/0/> * old alsa-devel archive at geocrawler <http://www.geocrawler.com/redir-sf.php?list=alsa-devel>"(http://www.alsa-project.org/main/index.php/Mailing-lists) Search for your card and other cards having the same chips like there are on your sound card. I GUESS a software mixer will be a remote control for an IO controller on your sound card.

Wonder, wonder, the ICE1724 might be not an advanced ICE1712, but it's an IO controler. As you can read there, it might be that the developers still need some time to solve all trouble for the mixer. It might be that there is no way to solve your trouble right now, but I didn't read the whole text. Maybe you need to use another sound card for Linux.

I don't know, but I don't think so. I guess the remote for the controllers is done by the ALSA drivers, resp. by applications like a mixer, using the ALSA driver. I guess it has nothing to do with JACK. If you are using JACK, the ALSA volume control should be fine. _______________________________________________ Jack-Devel mailing list Jack-Devel@... http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org |

Actually, the old emu10k1 based devices get great latency (less than 1ms) and some like my audigy2 ZS have 8 channels analog out and at least 4 in. Not a "professional" card by most standards but has worked great for me.

They seems to be less professional than my non-professional TerraTec EWX 24/96. You are able to keep latency at less than 1 ms what ever you do? My Envy24 card is able to start with a latency less than 1ms, but when working the latency must be set to higher than 10ms, for just 2 analogue IOs. Btw., I never tested if this will be fine. I've got AD/DA converters by DAT recorders, the drives are broken, but the converters and SPDIF are still fine. It might be possible, in addition to the 2 analogue channels, to add synced 2 channels by SPDIF. Dunno. Torsten keep in mind, that even if one 7.1 card is fine, you only can use 2 or more of those cards, if they can be synced.

It have 2 mono inputs and 4 mono outputs in 2 groups, main and monitor. From the card manual, the monitor outputs can only be used for direct input monitoring. I guess that it implies that it is no hardware volume control for the monitor outputs. In turn, this is not the job of ALSA (an hardware driver) to give you a volume control for an inexistant hardware volume control. But ALSA give you some switches for choosing the sources for the outputs (at least with the ICE1724). On the other hand, you can work at the software level with JACK and add as many mixer controls than wanted with software like jack mix or jack mixer.
