Re: [Alsa-user] Best supported cards?
I bought the M-Audio Audiophile 2496 PCI card based upon recommendations on this mailing list several years ago. Some people seem to have it working fine, but despite days of trying to configure it, I have never gotten it to work to it's full potential. If you understand the intricacies of sound in Linux, you probably stand a good chance of getting it to work well. Just don't expect to plug the card in and have everything work. Someday I will take a few weeks and see if I can follow the source code and read all the manuals for everything sound related in Linux. Until then I will just live with the problems. Here's what I have not been able to get to work: Full duplex, Recording in Audacity without introducing clicks into the captured audio, Getting Audacity to play without a few second delay and a bunch of clicks and pops, Getting Baudline to actually generate a tone, Getting xdemorse configured to recognize the sound card and getting various sound applications to actually share the card nicely. I have never even tried the S/PDIF I/O, so don't know if or how well it works. If you do get an Audiophile 2496 and get it working please document what you have done and post it. For me and a few others who don't understand all there is to know about sound in Linux, a how-to on this card would be most welcome.

Re: [Alsa-user] Best supported cards?
Here's what I have not been able to get to work: Full duplex, Not sure about the full duplex part, as not all cards are full duplex. My M-Audio Delta 44 says Full Duplex on the box. And seems to be just that. My laptop(ATI IXP) on the other hand can do full duplex, BUT... there's some bleed over of the playing track into the recorded track. And there's just too much noise from the plug-in power / bias voltage that powers electret style microphones. You might also try disabling the onboard soundcard in the bios/cmos. Or otherwise indexing the Audiophile's alsa driver to card 0. Or using defaults.pcm.card # in your asoundrc, where # is the card you want to use by default as shown in /proc/asound/cards. # in /etc/modprobe.d/alsa_custom # my own non distro supplied modules.conf style configuration # for my Delta 44 options snd-ice1712 index=0 # for my Mobile Pre options usb-audioindex=2 # note: my ati ixp takes up 0 AND 1 because of the ac97 modem part. # end alsa_custom # in ~/.asoundrc # when I'm too lazy to use jackd or re-index my drivers # or customize whatever sound app to use something other # than the default card(0). defaults.pcm.card 2 # where 2 is the card that I want to use # as listed in /proc/asound/cards # end .asoundrc Recording in Audacity without introducing clicks into the captured audio, Getting Audacity to play without a few second delay and a bunch of clicks and pops, I've found several things to cause this on my laptop. The cable running to the mic not quite being fully shielded from RFI. Even though it may claim to be shielded. Just don't put the cable on/near your LCD or CRT. The other cause is lack of realtime scheduling. i.e. If I'm doing some network traffic while recording. Solution below (for me anyway). # in /etc/security/limits.conf @audio - rtprio 99 @audio - nice -10 @audio - memlock unlimited # end of limits.conf In conjunction with using jackd -R -d alsa -d hw:0 -r 48000(as a user in the audio group, with the above mods. Or as root without.), I can get around the clicks and pops. You may have to recompile audacity to use port audio (v19) to use alsa natively. If your distro doesn't already do that. I find ardour to be a little more reliable in the recording department. On a side note, using a cell phone in close proximity to my audio gear seems to introduce some RFI to my stereo. Even having a cell phone that's on, but not currently in use will do some of that at random intervals. I know it's the cell phone because moving it to the other room stops affecting the gear in my room, and starts affecting it in the other room. Sort of a morse code D D as heard on my speakers when stereo is on and the cell phone is close enough to it. Just random static when actually using the cell phone. Apparently cell phones put out quite a signal. HTH - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Alsa-user] Best supported cards?
Hallo, Tom Lanyon hat gesagt: // Tom Lanyon wrote: The M-Audio cards are based on the Envy24HT chipset and are said to be well supported; can I assume that other cards using this chipset are well supported too? The Chaintech AV-710 is Envy24PT based and has digital toslink output. It's also available locally for $30-40. Cards based on the Envy chips (ICE1712, ICE1724) have high chances of being supported and the chips is very good in itself. However the chipset alone is no guarantee for a supported card, so it's better to take a look at the soundcard matrix. But even this is sometimes out of date, so an even better bet would be to use the source, Luke: If you can browse the ALSA sources, you may find references to cards in question. For your chaintech card, there are some promising results when grepping for chaintech in my (older) kernel sources: /usr/src/linux/sound/pci/ice1712/amp.c: /* Chaintech AV-710 has another codecs, which need initialization */ /usr/src/linux/sound/pci/ice1712/amp.c: .name = Chaintech AV-710, /usr/src/linux/sound/pci/ice1712/amp.h: {Chaintech,AV-710}, /usr/src/linux/sound/pci/ice1712/vt1720_mobo.c: .name = Chaintech ZNF3-150, /usr/src/linux/sound/pci/ice1712/vt1720_mobo.c: .name = Chaintech ZNF3-250, /usr/src/linux/sound/pci/ice1712/vt1720_mobo.c: .name = Chaintech 9CJS, /usr/src/linux/sound/pci/ice1712/vt1720_mobo.h: {Chaintech,ZNF3-150},\ /usr/src/linux/sound/pci/ice1712/vt1720_mobo.h: {Chaintech,ZNF3-250},\ /usr/src/linux/sound/pci/ice1712/vt1720_mobo.h: {Chaintech,9CJS},\ So it seems, at least someone has started to work on it. I don't know the status, though. Ciao -- Frank Barknecht _ __footils.org__ - This SF.net email is sponsored by: Microsoft Defy all challenges.

Tom According to this list AV-710 is well supported and is a cheap audiofiles' darling. Beware that not all DACs on AV-710 are created equal; I think people sw(itch|ap) front and rear DACs to be used to drive headphones - IIRC, however strange this may be, rear DACs are of better quality.

Re: [Alsa-user] Best supported cards?
Take a look at the M-Audio range of PCI cards. I think all of them have S/PDIF In and Out and they are supported by ALSA. The Audiophile range are pretty cheap but good quality (I don't have one but I've heard they are good) Otherwise as Jeremy suggested, the E-MU range is also pretty well supported by ALSA (apart from the USB cards if I remember correctly) and will be similar to the M-Audio range. -- Chris Stranex rm-rf - This SF.net email is sponsored by: Microsoft Defy all challenges.

I'm worried about interference on a coax cable back behind the receivers and would prefer an optical cable. 5 years ago the maudio transit (a usb card) already had an optical link. Not sure how well it works(I recall at least one complaint but do not know how it resolved) , but it is there. The card itself is very good for the analog output-- never tried the toslink, but then it is just a straight digital translation so not sure what could go wrong. Not sure why you would worry about interference, since the noise would have to be pretty high to start swamping the digital signal. Note that inside a computer is probably the worst place to put an audio card-- chock full of electronic interference. I think in principle a usb card is a far better, but of course practice conquors principle aways. Any other ideas? Thanks, Tom - This SF.net email is sponsored by: Microsoft Defy all challenges.
