Posted: Mon Aug 26, 2013 9:51 pm Post subject: alsaequal problems and workaround

I'm recently upgraded to gentoo 3.10 and alsamixer -D equal produced the following error

Code:

jes:/home/jes$ alsamixer -D equal
ALSA lib ctl_equal.c:268:(_snd_ctl_equal_open) Problem with control file .alsaequal.bin, 3 15.
cannot open mixer: Operation not permitted

A bit of playing with ebuild to get the source and examine the line in question in
/var/tmp/portage/media-plugins/alsaequal-0.6-r1/work/alsaequal-amd64/ctl_equal.c

Code:

264 if(equal->control_data->control[i].type == LADSPA_CNTRL_INPUT) {
265 index = equal->control_data->control[i].index;
266 if(equal->klass->PortDescriptors[index] !=
267 (LADSPA_PORT_INPUT | LADSPA_PORT_CONTROL)) {
268 SNDERR("Problem with control file %s, %d.", controls, index);
269 return -1;
270 }

Updating the SNDERR line to output the hex value of equal->klass->PortDescriptors[index] on errors showed it had a value of 0x15 which is LADSPA_HINT_LOGARITHMIC | LADSPA_PORT_INPUT | LADSPA_PORT_CONTROL, which triggers the error. Altering that line to be:

Code:

266 if((0xf & equal->control_data->control[i].type) == LADSPA_CNTRL_INPUT) {

then an ebuild compile/preinst/install/merge and a restart of alsasound restored the alsamixer ncurses equaliser to normal operation

Its actually a change in media-plugins/caps-plugins which added another value:

Code:

/* extending LADSPA_PORT_* */
#define LADSPA_PORT_GROUP (AUDIO<<1) /* 16 */
#define GROUP LADSPA_PORT_GROUP

The checks in media-plugins/alsaequal should really only validate the bits they need and not the whole bitset.

This is still a issue....happened to me just now, a year later. Any ideas?

Code:

localhost ~ # alsamixer -D equal
Failed to create secure directory (/root/.config/pulse): Not a directory
ALSA lib ctl_equal.c:268:(_snd_ctl_equal_open) Problem with control file .alsaequal.bin, 3.

btw caps-plugins are bit dated, 0.94 is latest version in the portage, there are 0.95 and 0.96 available. Didn't try 0.95 but the files directory (the patches) are not needed anymore in 0.96
