Package: audacity Version: 1.3.12-3 Severity: normal
Sorry for the delay of 5 days on this. I installed the 'audacity-dbg' package, and produced the following session with 'gdb': ---------- $ gdb /usr/bin/audacity GNU gdb (GDB) 7.1-debian Copyright (C) 2010 Free Software Foundation, Inc.

locals. ---------- Looking at the values of "j" (826) and "cnt" (4294967274) at the time of the crash, they look out of the ballpark to me. This is the loop being iterated (in lib-src/portmixer/src/px_linux_alsa.c) which hits those values: else if (snd_mixer_selem_is_enum_capture(elem)) { unsigned int cnt = snd_mixer_selem_get_enum_items(elem); unsigned int j; for (j = 0; j < cnt; j++) { char iname[256]; snd_mixer_selem_get_enum_item_name(elem, j, sizeof(iname), iname); snprintf(name, sizeof(name), "%s:%d", iname, snd_mixer_selem_get_index(elem)); dev->selems[i].vol = vol; dev->selems[i].item = j; dev->selems[i].elem = elem; dev->selems[i].index = snd_mixer_selem_get_index(elem); dev->selems[i].name = strdup(name); if (!dev->selems[i].name) { break; } i++; } The huge value for "cnt" suggests that snd_mixer_selem_get_enum_items() is returning a negative number here, but upstream has coded this function to store the return value in an unsigned int (and not bother to check it!). Looking for some documentation, I found: http://www.alsa-project.org/alsa-doc/alsa-lib/group___simple_mixer.html#g23600e756612dca7ea8329994590fa19 int snd_mixer_selem_get_enum_items (snd_mixer_elem_t *elem) Return the number of enumerated items of the given mixer simple element. Parameters: elem Mixer simple element handle Returns: the number of enumerated items, otherwise a negative error code Oops! This thing can return negative numbers, but upstream thought it wouldn't happen. What I would really like (from upstream? from a Debian patch?) is for 'audacity' to be able to run long enough for me to be able to configure it properly. On my system, ALSA picks up 3 different sound devices when the kernel boots, and the proper "card" to use for output is not the default card #0: $ dmesg | grep -i -A 3 alsa ALSA device list: #0: E-mu 0404b PCI [MAEM8852] (rev.0, serial:0x40021102) at 0xe800, irq 23 #1: HDA ATI SB at 0xfe7f0000 irq 16 #2: HDA ATI HDMI at 0xfe8ec000 irq 32 The first device is an inexpensive DSP card I use to plug in guitars; the second is the sound chipset on my motherboard (which would otherwise have been the default) and which I would like to use for sound output (/etc/asound.conf is configured for that purpose); and the third device the the HDMI outputs on my video card. As I mentioned when opening this bug report: the last time I used 'audacity' it worked fine. That was probably in January, unfortunately, and there have probably been several upgrades in versions of 'audacity' since then. I cannot say which upgrade version first showed this regression; I cannot even say which was the last working version! Sorry about that. If I can provide more information, test any patches, or be of help in some other way just let me know. Thanks, Dave W. PS: Sid changes frequently, and I upgraded from ALSA 1.0.22 to 1.0.23 (no change in 'audacity' regression behavior) to allow some other software to be brought in, so I am allowing 'reportbug' to list the full set of system information again.
