When you try to adjust the volume with alsamixergui, it hangs. straces shows the following: read(4, "\6\0\221\4\30\212X\0301\1\0\0\3\0\200\1\0\0\0\0\371\6\372"..., 32) = 32 ioctl(4, FIONREAD, [0]) = 0 ioctl(3, USBDEVFS_IOCTL, 0xbf83eed0) = 0 ioctl(3, USBDEVFS_HUB_PORTINFO, 0xbf83eed0) = 0 Then it hangs. my devices (/proc/asound/cards) 0 [Audigy2 ]: Audigy2 - Audigy 2 Platinum [SB0240P] Audigy 2 Platinum [SB0240P] (rev.4, serial:0x10021102) at 0xdf00, irq 225 1 [ICH7 ]: ICH4 - Intel ICH7 Intel ICH7 with ALC655 at 0xfdffe000, irq 225 Also worth noting that alsamixer (ncurses one) works just fine. gdb backtrace #0 0xb7e4d510 in snd_mixer_selem_id_set_index () from /usr/lib/libasound.so.2 #1 0xb7e4a07b in snd_mixer_selem_has_playback_channel () from /usr/lib/libasound.so.2 #2 0x0804e8ca in Fl_Menu_Button::~Fl_Menu_Button () #3 0x0804d1d1 in Fl_Menu_Button::~Fl_Menu_Button () #4 0xb7dd7305 in Fl_Valuator::handle_drag () from /usr/lib/fltk-1.1/libfltk.so.1.1 #5 0xb7dc8afb in Fl_Slider::handle () from /usr/lib/fltk-1.1/libfltk.so.1.1 #6 0xb7dc8ddc in Fl_Slider::handle () from /usr/lib/fltk-1.1/libfltk.so.1.1 #7 0xb7d9a17f in Fl_Window::flush () from /usr/lib/fltk-1.1/libfltk.so.1.1 #8 0xb7d9959f in Fl::handle () from /usr/lib/fltk-1.1/libfltk.so.1.1 #9 0xb7ddfa2b in Fl_Window::make_current () from /usr/lib/fltk-1.1/libfltk.so.1.1 #10 0xb7ddd18e in fl_wait () from /usr/lib/fltk-1.1/libfltk.so.1.1 #11 0xb7d98b1d in Fl::wait () from /usr/lib/fltk-1.1/libfltk.so.1.1 #12 0xb7d98c0f in Fl::run () from /usr/lib/fltk-1.1/libfltk.so.1.1 #13 0x0804b641 in Fl_Menu_Button::~Fl_Menu_Button () #14 0x08051c74 in Fl_Menu_Button::~Fl_Menu_Button () #15 0xb7b8609a in __libc_start_main () from /lib/tls/libc.so.6 #16 0x0804b091 in ??

Trying to track down the problem, I removed some USB devices. Turns out that a USB headset, which I do not have the module installed, on purpose, was unplugged alsamixergui worked as expected. It's just a standard usb headset, uses the usb-audio module. But if it isn't loaded in the kernel I don't see how this should effect alsamixer one bit. As shown, it isn't listed in /proc/asound/cards.
Anyone going to respond to this bug?

Not much has happened, but sounds like an upstream issue with alsa. Does this still happen with the current alsa-lib version (considering that is stucks inside asound.so)?
(In reply to comment #2) > Anyone going to respond to this bug? Seems to work fine, can you reproduce with current alsa? Reopen, if you can.
