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: 08-05-2006 02:10 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 - 08-01-06 09:07 ---------------------------------------------------------------------- Do any GPIO pins of envy24ht connected to IC other than the 3 AKM ICs ? https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1090#5457 I can only tell you that you don't need GPIO_ANALOG_PRESENT since audiophile 192 cannot detach the daugther card like juli. Ask the expert about the values of AKxxxx_ADDR You have to check the other define GPIO_XXX are correct by reading the datasheet and the wiring Ask any user with juli about how GPIOs are connected to understand the relationship of bit shift (1<< ??) and pin number (e.g. GPIO_ANALOG_PRESENT can be easily traced in juli) If you don't post the wiring info, how can other help you ? Find out how to make the the driver know DAC is SND_AK4358 ADC is SND_AK5385 SPDIF is AK4114 Follow rlrevell's instruction in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1090 to test the new driver. /* other board-specific data */ union { struct { ak4114_t *ak4114; unsigned int analog: 1; } juli; + struct { + ak4114_t *ak4114; + } ap192; } spec; ---------------------------------------------------------------------- Raymond - 08-05-06 02:10 ---------------------------------------------------------------------- >> Ok, i got the wiring between between the vt1724 and the 3 dacs (AKMs) how do i >> code this into the driver, >> is there any example, i looked at juli.c and i couldnt understand the /* GPIO Pins */ Those define GPIO_XXXXX were not used in juli.c , it seem to be just a description of those GPIOs connected to XXXXX (pin of the target or function) since juli does not get the dir,mask from EEPROM data. In you case, AP192 has EEPROM and the gpio are initialised by the values from EEPROM. Do your AP192 GPIO wiring different from juli ?
