[alsa-devel] [PATCH] ASoC DAPM switching for reentrant codec paths.
by Liam Girdwood 16 Apr '07

16 Apr '07

This patch fixes an issue whereby power was applied to any inactive analog path that would leave and reenter a codec (e.g. ACOP -> ACIN on WM8753). This change now checks for such paths and DAPM will power them down when not in use.

[alsa-devel] [PATCH] ASoC WM9712 kmemdup
by Liam Girdwood 16 Apr '07

16 Apr '07

This patch creates the WM9712 codec register cache using kmemdup instead of doing a kzalloc followed by a memcpy. Signed-off-by: Graeme Gregory <gg(a)opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lg(a)opensource.wolfsonmicro.com>

[alsa-devel] HDA Intel - Conexant CX20549 loaded but not working
by S Boucher 15 Apr '07

15 Apr '07

Using alsa-driver-1.0.14rc3 I have the following problems: - cannot record from internal mic (of an hp dv6245) - spdif not working - using jack I get lots of xruns (I don't get any xrun on the exact same system if I use an M-Audio Transit, so I'm assuming something ain't kosher in the conexant driver) - I was able to record cleanly from ext mic (although I had to select int mic) I'm with Ubuntu Feisty. N E Waze, if I can be of assistance let me know soon. The nice HP DV6245 laptop is heading back to the store in 1-2 days (nice system, except I don't have time to learn sign language :-)). __________________________________________________ Do You Yahoo!?

[alsa-devel] Kernel crash with 2.6.20.x : snd-usb-audio implicated...
by Chris Rankin 15 Apr '07

15 Apr '07

Hi, The 2.6.20.x kernels all crash on my SMP-HT machine, and the oops report always shows that udev was trying to access an endpoint belonging to the snd-usb-audio driver. The frustrating part is that this particular endpoint shouldn't even exist! (It doesn't exist whenever I check the /sys/class/usb_endpoint directory.) Is there any way that userspace ("winecfg" in my case) can cause the snd-usb-audio driver to switch from (If# = 2, Alt = 0) to (If# = 2, Alt > 0) please? Because that is currently the only way that I can see this endpoint ever being created.

[alsa-devel] function location?
by Ashlesha Shintre 13 Apr '07

13 Apr '07

Hi, I am trying to write an application to just play a wave file and record sound using ALSA -- I looked at the pcm_min.c file and tried to run it - I am using UBUNTU and 1.0.11-7ubuntu3 sound library called libasound2. I cant seem to find the pcm.c file which has all the snd_pcm_open and other functions used in the pcm_min.c file! I am using : /usr/include/alsa/asoundlib.h header -- but i m not sure where the functions defined in this header are -- and, find / -name pcm.c yields nothing --nor does find / -name snd_pcm_open Any pointers please! Thanks, Ashlesha.

[alsa-devel] 1010lt (ice1712) asoundrc for 6 virtual mono cards question
by Giovanni Maruzzelli 13 Apr '07

13 Apr '07

Dear Alsa developers, I want to use a 1010lt (ice1712 driver) as 6 analog mono duplex cards. I want to use the /etc/asound.conf (.asoundrc) to split the card (that has 8 in and 8 out - but I use just 6 in/out), with minimal latency. I mean, I want to record and play (duplex) from/to each virtual card concurrently and from separate application instances. My app works with S16_LE, 8000, mono. Is the following asound.conf (.asoundrc) correct and efficient for this? I got spikes of cpu load (at 5-6%) on each virtual card any roughly 256 seconds when using a(play|record) to record or play from/to any channel, and the spikes cumulate with the number of virtual cards concurrently in use (eg. if I use 6 virtual cards concurrently I got spikes of 30% cpu load each 256 seconds). I need to create ctls? It would behave better if I use an asym to link toghether each couple of input and output? Any hints? Thanks a lot in advance, Giovanni that is the /etc/asound.conf I'm using: pcm.capt { type dsnoop ipc_key 223456 slave { pcm "hw:0,0" rate 8000 period_time 0 period_size 320 channels 12 format S32_LE } } pcm.capt3 { type plug slave.pcm capt ttable.0.2 1 } pcm.capt4 { #used type plug slave.pcm capt ttable.0.3 1 } pcm.capt5 { type plug slave.pcm capt ttable.0.4 1 } pcm.capt6 { type plug slave.pcm capt ttable.0.5 1 } pcm.capt7 { type plug slave.pcm capt ttable.0.6 1 } pcm.capt8 { type plug slave.pcm capt ttable.0.7 1 } ############################# ############################# pcm.s3 { type dshare ipc_key 123456789 slave { pcm "hw:0,0" rate 8000 period_time 0 period_size 320 channels 10 format S32_LE } bindings { 0 2 } } pcm.play3 { type plug slave.pcm s3 } pcm.s4 { type dshare ipc_key 123456789 slave { pcm "hw:0,0" rate 8000 period_time 0 period_size 320 channels 10 format S32_LE } bindings { 0 3 } } pcm.play4 { type plug slave.pcm s4 } pcm.s5 { type dshare ipc_key 123456789 slave { pcm "hw:0,0" rate 8000 period_time 0 period_size 320 channels 10 format S32_LE } bindings { 0 4 } } pcm.play5 { type plug slave.pcm s5 } pcm.s6 { type dshare ipc_key 123456789 slave { pcm "hw:0,0" rate 8000 period_time 0 period_size 320 channels 10 format S32_LE } bindings { 0 5 } } pcm.play6 { type plug slave.pcm s6 } pcm.s7 { type dshare ipc_key 123456789 slave { pcm "hw:0,0" rate 8000 period_time 0 period_size 320 channels 10 format S32_LE } bindings { 0 6 } } pcm.play7 { type plug slave.pcm s7 } pcm.s8 { type dshare ipc_key 123456789 slave { pcm "hw:0,0" rate 8000 period_time 0 period_size 320 channels 10 format S32_LE } bindings { 0 7 } } pcm.play8 { type plug slave.pcm s8 }
