Hi Mark, The following two patches fix 2 issues in the updated au1x asoc drivers in your/Takashis queue for 2.6.33. If possible, please either fold them into commit 0f83d639d84c99a775c60696dbde77372c2cf4ac ("au1x: convert to platform drivers") found in Takashi's tree. Thank you!

[alsa-devel] ASoC: OMAP mcbsp: dai->dev is missing warning
by Peter Ujfalusi 03 Dec '09

03 Dec '09

Hello, Recently the following warnings appeared during the bootup on OMAP platforms: No device for DAI omap-mcbsp-dai-0 No device for DAI omap-mcbsp-dai-1 No device for DAI omap-mcbsp-dai-2 No device for DAI omap-mcbsp-dai-3 No device for DAI omap-mcbsp-dai-4 I have taken a look, and it is printed, because the dai->dev is NULL for OMAP McBSP DAIs. Also the comment there states, that the dai->dev will become mandatory in the future. At the moment the platform device/driver is not used for the sound/soc/omap/omap-mcbsp, it is used for the arch/arm/plat-omap/mcbsp.c, so we really don't have possibility at the moment to provide a valid dai->dev for ASoC at the moment. Mark: Do you have some estimates, when the dai->dev will become mandatory? Jarkko: Shall we start to think about the possibilities to provide a valid dai- >dev for the mcbsp DAIs? -- Péter

[alsa-devel] testing mic-in for tlv320aic33
by vivek kaushik 03 Dec '09

Hi All, I am testing MIC IN on tlv320aic33. but getting the following error: arecord: pcm_read:1338: read error: Input/output error On my custom board tlv320aic33 is connected mcbsp-1 of omap3530, i am configuring tlv as mater and omap3530 as slave.aplay is working fine for me but getting the above error in case of arecord. I am testing MIC IN with following command arecord -fdat record.wav when i probe signals I am getting proper MCLK, WCLK(48khz) and BCLK(1.5Mhz) but there is no toggling on data line. would be grateful to any help Thanks in advance Cheers Vivek

[alsa-devel] hw_ptr accuracy with intel8x0 -> PulseAudio issue
by pl bossart 03 Dec '09

03 Dec '09

Hi, I have been having issues for a while now with PulseAudio running on an older Thinkpad X41. PulseAudio relies on snd_pcm_avail() to detect underflows and increases the timer watermark when they happen. There are actually no audible underflows though... So I instrumented both PulseAudio (enabling DEBUG_TIMING in the alsa-sink.c code) and the kernel (latest alsa-kernel git) by adding the following printk in pcm.h: static inline snd_pcm_uframes_t snd_pcm_playback_avail(struct snd_pcm_runtime *runtime) { snd_pcm_sframes_t avail = runtime->status->hw_ptr + runtime->buffer_size - runtime->control->appl_ptr; if (avail < 0) avail += runtime->boundary; else if ((snd_pcm_uframes_t) avail >= runtime->boundary) avail -= runtime->boundary; //plb if(avail > runtime->buffer_size) { snd_printk(KERN_ERR "avail %d hw_ptr %d buffer %d appl_ptr %d \n", avail, runtime->status->hw_ptr, runtime->buffer_size, runtime->control->appl_ptr); } return avail; } In my tests this error condition where avail is larger than the ring buffer happens fairly often. The dmesg log show messages such as [ 834.524479] ALSA include/sound/pcm.h:600: avail 16403 hw_ptr 24351 buffer 16384 appl_ptr 24332 [ 835.266937] ALSA include/sound/pcm.h:600: avail 16407 hw_ptr 55841 buffer 16384 appl_ptr 55818 and these messages are correlated with the times when PulseAudio detects underflows. The full log can be found at http://pastebin.com/f210aa108. I believe the issue is the accuracy of the hw_ptr reported by snd_intel8x0_pcm_pointer. If indeed such a condition occurred, it should be flagged as underflow, shouldn't it? There's been some changes in this part of the code to avoid extremely large values, here the issue seems more subtle, the pointer is only slightly off in most cases. This does screw-up PulseAudio though, the timer watermark keeps increasing and low-latency isn't possible. I'd be more than happy to run more experiments, however I have no idea what the hardware does to report the position of the hw pointer. Thanks for your feedback - Pierre

[alsa-devel] rewind operations in pcm_ops
by Singaravelan Nallasellan 02 Dec '09

02 Dec '09

Hi, The audio subsystem in platform has its own buffering. It could buffer upto 256KB. Our driver uses indirect callback to send the buffers and sizes to audio subsystem whenever the "ack" is called. If rewind is required during the playback, ALSA pcm native interface is not calling the driver operations for rewind. I am planning to add rewind operations to pcm_ops and make changes to pcm files. Please suggest me whether this is acceptable. Thanks -Sing
