This is a followup to a message I wrote nearly a year ago, but the problem has finally only been resolved today (at least that which could be resolved). I felt a followup might be useful to others who may encounter the same problems or come up with the same questions ... On Sun, 23 Mar 2003, I wrote: > The computer system is a 400 MHz K6-2 with 512 MB memory, and a Hercules > Fortissimo II (Cirrus Logic Soundfusion CS4624 processor) sound card.

After having spent the last six months or so with the system in a basically unusable state (for an unrelated reason), I have finally upgraded to Slackware-9.1 (Linux-2.4.22), and installed alsa-driver-0.9.8, alsa-lib-0.9.8 and alsa-utils-0.9.8. > ALSA is the only component that I have modularized ... still true ... > I can send sound to the computer, and listen to that sound coming back > from the computer (adjusting the level with the "line" level in Aumix, > for example), but if I try to record that sound (in any of the > applications I've tried, including all those listed above), with "record > enable" selected in Aumix, I get no audio recorded (silent sound file). I have finally resolved this issue, thanks to a note I found at the "ALSA HOWTO WIKI" (http://alsa.opensrc.org/) On the page which discusses the cs46xx driver (http://alsa.opensrc.org/index.php?page=cs46xx), I noticed this paragraph referring to the Midiman DMAN card: If you find you can't record with this card, open up the alsamixer and set the following 3 channels to "capture": LINE, CAPTURE, and ADC. You of course have to unmute and set levels, but it takes all 3 of these channels set to capture mode in order to record on the Midiman DMAN. I tried this on my own card, found that it works (finally, I can record using this soundcard!), and added a note that this also applies to the Hercules Gamesurround Fortissimo II soundcard. Thanks to who-ever took the time to post that information about the DMAN card! > Also, I find it interesting to note that I can record-enable only one > input source at a time ... still true. I'm still assuming this is a limitation in the hardware. > - Can someone point me in the right direction(s) to find a solution to > this, so I can record audio (preferably from numerous sources) into > my computer? Resolved! :-) (at least for a single source; I'm using a hardware mixer anyway, so it isn't critical that I'm unable to record-enable multiple sources) [ starting jackd at boot-time ] > Jackd fails to start at that point ... but it does start when > run manually from a root shell. Still unresolved. I'm no longer certain that I'll want to run Jack at boot-time, as it seems I may want to not use it with some applications (someone please correct me if I'm wrong about that...) > - Is it possible to build ALSA into the kernel? I'd still like to do this, but it isn't critical. > - on a slightly unrelated point, my new soundcard has a built-in > synthesizer with at least some features I'd like to explore. It has become clear to me that the cs46xx ALSA driver does not contain support for the built-in synth on these cards. Is this due to lack of documentation? lack of interest? other? It has taken a lot of patience, and much more work than I expected, but I finally have a computer which I may be able to once again use for recording and sequencing (Audacity works and Rosegarden-4 is looking very nice... Ardour is most definitely going to be looked at!) Much thanks is owed to all those who have contributed to the software and documentation which has made this possible. Perhaps I can repay the favour someday ... -- ---------------------------------------------------------------------- Sylvain Robitaille syl@xxxxxxxxxxxxxxxxxx Major in Electroacoustic Studies Concordia University Faculty of Fine Arts / Music Department Montreal, Quebec, Canada ----------------------------------------------------------------------
