Responsible Changed From-To: freebsd-bugs->sound Old sound-related PR; is this still relevant? State Changed From-To: open->closed Voxware driver is long deprecated. This patch fell through the cracks and is not relevant to the current sound arch. |
Attached is the patch which enables basic ISA ESS based soundcard support for VoxWare sound driver(/sys/i386/isa/sound). * The new ess_init() routine should recognize following chips: ESS 488/688/1788/1868/1869/1878/1887/1888 * Support 16 bits audio playback/record * Audio capabilties displayed via "mpg123 -vv": | s16 | u16 | u8 | s8 | ulaw | alaw | -------------------------------------------------------- 8000 | M/S | | M/S | | M/S | | 11025 | M/S | | M/S | | M/S | | 12000 | M/S | | M/S | | M/S | | 16000 | M/S | | M/S | | M/S | | 22050 | M/S | | M/S | | M/S | | 24000 | M/S | | M/S | | M/S | | 32000 | M/S | | M/S | | M/S | | 44100 | M/S | | M/S | | M/S | | 48000 | M/S | | M/S | | M/S | | * This patch has been tested on my laptop(ESS1869 built-in) for a couple of months. * This PR fixed a bug in PR/12113 which may lead to infinite waiting while user-land applications do DMAbuf_sync() related operations; therefore, PR/12113 should be closed. Fix: Which were not included in following patch: * MIDI playback. * Full duplex mode. * ESS 1887 specific record setting. * The ess_XXXX related routine should be kept into a separated file; however, it seems that some other SB-clone drivers(JAZZ 16, SoundMan Wave) shared the common routine(sb_XXXX) in sb_dsp.c & sb_mixer.c. Any volunteer wants to tidy them up? How-To-Repeat: Please check & commit this patch, thanks. Patch has been tested on 3.2-STABLE ~ 3.3-RELEASE series.
