A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1823> ====================================================================== Reported By: darkbrain Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 1823 Category: PCI - cs46xx Reproducibility: always Severity: major Priority: normal Status: new Distribution: Kernel Version: ====================================================================== Date Submitted: 02-05-2006 22:59 CET Last Modified: 07-25-2006 02:41 CEST ====================================================================== Summary: surround40 memory leak Description: It seems that surround40 has a memory leak or somthing similar, playing a game in surround40 mode the game result unplayable after some minutes. And there is a problem in CS46xx.conf file, i need to remove the hook on the rear pcm to permit multiple surround40 subdevices to be opened. ====================================================================== ---------------------------------------------------------------------- bitmage2 - 07-24-06 21:25 ---------------------------------------------------------------------- Raymond, in case that you still need information about the "value return by snd_pcm_info_get_subdevices_count()", I did a small test program (see below): chris@bjork:~> /opt/SVN/branches/3.5/kdemultimedia/kmix/a.out snd_pcm_open() = 0 snd_pcm_info_get_subdevices_count() = 0 ; sizeof= 288 ---------------------------------------------------- #include <alsa/asoundlib.h> main() { snd_pcm_t *pcm; int ret; const snd_pcm_info_t *obj; ret = snd_pcm_open(&pcm, "surround40", SND_PCM_STREAM_PLAYBACK, SND_PCM_NONBLOCK) ; printf ( "snd_pcm_open() = %i\n", ret); ret = snd_pcm_info_get_subdevices_count(obj); printf ( "snd_pcm_info_get_subdevices_count() = %i ; sizeof= %i\n", ret, snd_pcm_info_sizeof() ); } ---------------------------------------------------------------------- Raymond - 07-25-06 02:41 ---------------------------------------------------------------------- I am just a reporter and do not have any cs46xx card too. Whether cs46xx support multiple instances of multi-channels seem depend on DSP firmware Can you run multiple instances of surround40 and surround51 concurrently (speaker-test or 5.1 movie) by removing the lock in CS46xx.conf I want to find out a feasible solution (period_size, period and buffer_size calculation by snd_pcm_set_params() ) for my au8830 sound card in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1724 by comparing au8830 (device 0 support 1, 2, 4 channels) with cs46xx (multi pluginn of device front, rear and center_lfe). Can you try alsa-lib example (i.e. alsa-lib/test/pcm_min.c) ? I will upload a modifed version which test difference devices (hw:0, front, surround40, surround51) with 1, 2, 4, 6 channels and format S16_LE in snd_pcm_set_params() and print out the values of period_size and buffer_size returned by snd_pcm_get_params() BTW, you forget to call snd_pcm_info(pcm, obj) in your program Issue History Date Modified Username Field Change ====================================================================== 02-05-06 22:59 darkbrain New Issue 02-06-06 06:32 Raymond Note Added: 0007943 02-06-06 07:10 Raymond Note Edited: 0007943 02-06-06 07:31 Raymond Note Edited: 0007943 02-06-06 07:32 Raymond Note Edited: 0007943 02-06-06 10:46 darkbrain Note Added: 0007945 02-06-06 10:46 darkbrain Note Added: 0007946 02-06-06 10:47 darkbrain Note Deleted: 0007946 02-06-06 18:37 darkbrain Note Added: 0007950 02-11-06 15:01 darkbrain Note Added: 0008018 02-12-06 05:09 Raymond Note Added: 0008025 02-15-06 06:21 Raymond Note Added: 0008076 02-21-06 07:56 Raymond Note Added: 0008152 03-27-06 04:42 Raymond Note Added: 0008987 06-02-06 09:33 Raymond Note Deleted: 0008152 06-02-06 09:33 Raymond Note Deleted: 0008987 06-02-06 09:34 Raymond Note Deleted: 0008076 07-11-06 13:28 Raymond Note Added: 0010970 07-24-06 21:21 bitmage2 Note Added: 0011215 07-24-06 21:25 bitmage2 Note Added: 0011216 07-25-06 02:41 Raymond Note Added: 0011222 ====================================================================== ------------------------------------------------------------------------- Take Surveys.
