Hi, all! I have problems making any sound with current linux-omap master. Driver below worked ok with 2.6.28-omap1, and debugging output of mcbsp driver is the following: gnome5:~# aplay -c 2 -f S16_LE /dev/urandom [ 4593.480072] !!!omap_mcbsp_dai_startup() [ 4593.484283] !!!omap2_mcbsp_request() [ 4593.488159] disabling LINE_OUT [ 4593.491302] disabling DMIC [ 4593.494018] Disabling ASSYM pin Playing raw data '/dev/urandom' : Signed 16 bit Little Endian, Rate 8000 Hz, Stereo [ 4593.522064] !!!omap_mcbsp_dai_set_dai_fmt() [ 4593.615905] !!!omap_mcbsp_dai_hw_params() [ 4593.620086] omap-mcbsp omap-mcbsp.2: Configuring McBSP2 phys_base: 0x49022000 [ 4593.678375] gnome5_jack_event [ 4593.726623] !!!omap_mcbsp_set_threshold() [ 4593.730651] !!!omap_mcbsp_dai_trigger() [ 4593.735015] omap-mcbsp omap-mcbsp.2: **** McBSP2 regs **** [ 4593.740539] omap-mcbsp omap-mcbsp.2: DRR2: 0xd907da5a [ 4593.745697] omap-mcbsp omap-mcbsp.2: DRR1: 0x0000 [ 4593.750518] omap-mcbsp omap-mcbsp.2: DXR2: 0x0000 [ 4593.755340] omap-mcbsp omap-mcbsp.2: DXR1: 0x0000 [ 4593.760162] omap-mcbsp omap-mcbsp.2: SPCR2: 0x02f5 [ 4593.764984] omap-mcbsp omap-mcbsp.2: SPCR1: 0x0030 [ 4593.769805] omap-mcbsp omap-mcbsp.2: RCR2: 0x8041 [ 4593.774627] omap-mcbsp omap-mcbsp.2: RCR1: 0x0040 [ 4593.779449] omap-mcbsp omap-mcbsp.2: XCR2: 0x8041 [ 4593.784271] omap-mcbsp omap-mcbsp.2: XCR1: 0x0040 [ 4593.789093] omap-mcbsp omap-mcbsp.2: SRGR2: 0x001f [ 4593.793884] omap-mcbsp omap-mcbsp.2: SRGR1: 0x0f00 [ 4593.798706] omap-mcbsp omap-mcbsp.2: PCR0: 0x000f [ 4593.803527] omap-mcbsp omap-mcbsp.2: *********************** [ 4603.811187] ALSA sound/core/pcm_lib.c:1708: playback write error (DMA or IRQ trouble?)

Codec is supplied properly with clock, and programmed normally, so I think that's McBSP trouble, but I might be wrong. I use tlv320aic32 as codec. I use slightly modified sound/soc/omap/n810.c with clock names changed for OMAP3. Clock is supplied properly. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
