A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2287> ====================================================================== Reported By: cruiseoveride Assigned To: ====================================================================== Project: ALSA - lib Issue ID: 2287 Category: 0_general Reproducibility: always Severity: crash Priority: normal Status: new ====================================================================== Date Submitted: 07-16-2006 18:03 CEST Last Modified: 07-19-2006 06:21 CEST ====================================================================== Summary: Segfaults all functions after snd_pcm_hw_params_get_buffer_size (params,(snd_pcm_uframes_t *) & val); Description: I am new to Alsa and am not happy at all at the state of documentation available. You guys seriously need to do something about this. I have an M-Audio Audiophile Delta 192 (ICE1724) and I want to port envy24control for this chip, However I first need to familiar myself with the ALSA API. So I began by looking for simple examples on how to use ALSA API and came accross the followinf prog (Attached file test.c). The program compiles cleanly with gcc-4.1 and runs, however after it prints out the ..."buffer size = 8192 frames" It segfaults. If you slash out line 104, it resolves the issue. My question is, Is there a bug in this function? Code was obtained from http://www.linuxjournal.com/article/6735 ====================================================================== ---------------------------------------------------------------------- Raymond - 07-19-06 03:27 ---------------------------------------------------------------------- http://hg-mirror.alsa-project.org/alsa-kernel?fl=62e077ee4855;file=pci/ice1712/ice1724.c;style=gitweb http://alsa.opensrc.org/ice1724 http://alsa.opensrc.org/index.php?page=Envy24Control It seem that Audiophile Delta 192 is not supported You will need to open bug reports for 1) Audiophile Delta 192 2) envy24control for ice1724 ---------------------------------------------------------------------- Raymond - 07-19-06 06:21 ---------------------------------------------------------------------- Audiophile Delta 192 seem not supported Can you playback/capture any stereo sound ? You have to idenify the sound chip http://www.via.com.tw/en/products/audio/controllers/ and those AK4xxx ADC/DAC on your card http://hg-mirror.alsa-project.org/alsa-kernel?cmd=file;file=pci/ice1712/ak4xxx.c;filenode=d9808d13fa5fa018617ba56852cdc6473a7a35af;style=raw Find out the specification of your card and compare the specification of other ice1724 cards. Find out the specification of those ADC/DAC on your card. Study those ice1724 driver code (e.g. aureon.c, ... ) and see whether you can find any cards have similar features/architecture (e.g. same ADC/DAC, ...) with your card. It is impossible to write a new driver by using the control 'multi track peak' which is only an abstract control.
