[alsa-devel] Laptop (Samsung Q45) speakers unmute when master channel is unmuted even with headphones connected
by Sam Morris 07 May '09

07 May '09

Since Linux 2.6.28 and through to 2.6.30-rc4, the hda-intel driver has had a bug on my laptop (a Samsung Q45). If I connect my headphones, the laptop's internal speakers are muted--fine. But if I then mute and unmute the master mixer channel, the speakers come back to life, even though the headphones are still connected. Please keep 517241-forwarded(a)bugs.debian.org CC'd in follow-ups. -- Sam Morris https://robots.org.uk/ PGP key id 1024D/5EA01078 3412 EA18 1277 354B 991B C869 B219 7FDB 5EA0 1078

Hi, If I use the format SNDRV_PCM_FORMAT_GSM to identify if the audio stream is voice stream or not, would it be appropriate? Thanks, Harsha

I have not heard from this kind of problem so far, which does not mean, that it does not exist ;) Can you describe the beep sound? After a quick look I can not pin point the soc board file used with the omap3evm board. Is it in the tree?

Re: [alsa-devel] [Intel] RE: How to play second stream in linux
by Yang, Brandon 07 May '09

07 May '09

Hi Takashi, Thanks for your guidance. I had added some code to play second stream in HD audio driver. Our PM would like us to upstream the source code. He thinks it would be more convenient for customer if they can download the code from ALSA. Our source code is base on kernel 2.6.24.2 and specific to ALC262. As you know, some of our code is hard-coded for our platform. I don't know whether this code can meet your requirement or not. If it can meet your requirement, please help me to upstream it. Thanks very much. The attached file is the patch file. Best Regards, Brandon
