#6988: System speaker remains active with audio file playback ----------------------------+------------------------------------------- Reporter: Meanwhile | Owner: korli Type: bug | Status: new Priority: normal | Milestone: R1 Component: Drivers/Audio | Version: R1/Development Resolution: | Keywords: MediaPlayer, system speaker Blocked By: | Has a Patch: 0 Platform: All | Blocking: ----------------------------+------------------------------------------- Comment (by Meanwhile): Replying to [comment:8 stargatefan]: > what model of laptop is this ? and do you know what motherboard revision is involved, what behaviors do you get on another OS say windows where the audio is well supported ? It's desktop PC, a Dell GX280. Can the motherboard revision be read from the BIOS Serial number? Maybe it's printed on the motherboard? The same PC also runs Windows XP (my HDD has a Windows and a Haiku partition), and XP behaves as it should in this respect. Maybe you know a place inside Windows XP that shows the rev. number to the user? > It would help in diagnosing the problem. you do get sound now however correct ?this could be a hardware design issue. Yes, I get sound, but the system speaker joins in on it. > > here is the chipset pdf. I am trying to see how many audio layouts one could generate with such a chip. its likely the output may all be internally connected and there is additional control implementation on the chipset to configure which audio circuts are active. > > thats the datasheet > > > http://www.google.com/url?sa=t&source=web&cd=1&ved=0CBMQFjAA&url=http%3A%2F%2Fwww.intel.com%2FAssets%2FPDF%2Fdatasheet%2F301473.pdf&rct=j&q=Intel%20ICH6%20&ei=gDIMTdbeBs2jnQfErLH5DQ&usg =AFQjCNEOj7nJSrVbp9O3mdF5Bx-mHoTqMw > > white paper briefing describing chip capabilitys. > > http://www.google.com/url?sa=t&source=web&cd=2&ved=0CBgQFjAB&url=http%3A%2F%2Fwww3.intel.com%2FAssets%2FPDF%2Fappnote%2F301462.pdf&rct=j&q=Intel%20ICH6%20&ei=gDIMTdbeBs2jnQfErLH5DQ&usg=AFQjCNEaZKLrD1FuqiWAUR8X5_XJQMTH1g > > its entirely possiable depending on how the implemented certain features on teh chip that the oss driver doesn't fully support your MB layout. I didn't have this problem in an earlier Haiku revision (I'm pretty sure r38360 was okay). Also, the problem manifested itself before I removed the native auich driver and switched to OSS.[[BR]] To sum up: I once ran a Haiku revision using the auich driver with no problem (pretty sure that's r38360).[[BR]] Then, a later Haiku revision (that used the auich driver) had this problem.[[BR]] After that, removing the auich driver and installing the OSS one didn't remove the problem. So it seems to me it's not an OSS or motherboard incompatibility problem? -- Ticket URL: <http://dev.haiku-os.org/ticket/6988#comment:9> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
